Summary

As Andy Burnham became UK prime minister on 20 July 2026 promising faster, fairer growth, the scale of the task can be read through seven recurring charts. The first two describe a weak growth engine: productivity per hour has grown slowly since the 2008 crisis, and business investment sits near the bottom of the G7 as a share of GDP. The next three show the living-standards squeeze: real wages have barely risen in a decade and a half, output per person in London far exceeds most other regions, and industrial electricity prices are among the highest in the developed world. The final two set the fiscal limit: gilt yields have risen and public debt is near 100 per cent of GDP. Read together, and with the IMF warning against unfunded spending, the charts explain why cheap, quick growth is not available and why Burnham faces hard choices rather than easy wins.

Five Key Takeaways

  1. Burnham inherits an economy whose core weakness is productivity: without faster output per hour, higher wages and better services require ever more borrowing.
  2. Regional inequality is both a political mission for the 'King of the North' and a statistical fact, with London far ahead of most other areas.
  3. Low business investment and expensive energy are linked problems that blunt the private-sector growth Burnham needs to fund his promises.
  4. The fiscal room is narrow: gilt yields have risen, public debt is near 100 per cent of GDP, and the IMF warns against unfunded spending.
  5. Real wages have stagnated for years, which is why cost-of-living relief sits at the centre of Burnham's message and his political risk.

What Happened

Andy Burnham walked into Downing Street on Monday 20 July 2026 having promised to boost growth across every part of the country. He is Britain's 59th prime minister and the seventh in a decade, and he inherits an economy that has frustrated a long line of predecessors. Around the handover, the Financial Times set out the scale of the task in a familiar format: a survey of the charts the incoming prime minister most needs to understand.

This article follows that framing. Each chart is illustrative — a way of seeing a well-documented trend rather than a single fresh data point — and together they explain why Burnham's growth pledge is so demanding.

The seven are these. First, productivity: a line showing output per hour growing far more slowly since the 2008 financial crisis than in the decades before. Second, regional inequality: a bar chart in which London and the South East tower over much of the North, the Midlands and the coastal periphery. Third, business investment: a comparison in which the UK sits near the bottom of the G7 as a share of national income.

Fourth, gilt yields: a chart climbing away from the near-zero borrowing costs of the 2010s. Fifth, real wages: pay that, after inflation, has barely moved across a decade and a half. Sixth, public debt: net debt hovering close to 100 per cent of GDP, around its highest since the early 1960s. Seventh, energy: industrial electricity prices that rank among the most expensive in the developed world, a pressure sharpened by the energy-price effects of the Iran war.

None of these charts is a surprise to the Treasury. What is new is the political context. Burnham has staked his premiership on faster, fairer growth and on cost-of-living relief, and he has said he will 'use any flexibility' within the fiscal rules to invest. The charts define the space in which that ambition must operate.

Why It Matters

These seven pictures matter because they are not separate problems; they are one problem seen from different angles. Productivity — how much the economy produces for each hour worked — is the master variable. When it grows, wages, tax revenues and public services can all improve without extra borrowing. When it stalls, as it largely has since 2008, every other ambition becomes harder and more expensive to fund.

For a prime minister who has promised to ease the cost of living, the real-wage chart is the most politically charged. Households do not feel gross domestic product; they feel their pay packet against their bills. A long stretch in which pay has barely outpaced prices is the lived experience behind Burnham's affordability message, and it is why voters will judge him on outcomes rather than announcements.

The regional chart speaks directly to Burnham's identity. As the former mayor of Greater Manchester and the self-styled 'King of the North', he has built a career on the argument that too much of Britain's prosperity is concentrated in and around the capital. The data supports the grievance: the gap in output per person between London and many other regions is among the widest in the developed world. Closing even part of it is central to his claim to govern for 'every part of the United Kingdom'.

The investment and energy charts explain why private-sector growth has been so hard to ignite. Firms that face some of the highest electricity costs in the rich world, and that have invested less than their G7 peers for years, are unlikely to power a sudden productivity revival on their own. That is the concern behind the FT's warning that Britain must revive its 'animal spirits' rather than lean on the state.

Finally, the gilt-yield and debt charts set the hard limit on everything else. Higher borrowing costs and a debt burden near 100 per cent of GDP mean the Treasury has little slack. The IMF has cautioned that Burnham cannot afford an unfunded surge in spending, and that any response to the energy-price shock should stay 'targeted, temporary and budget-neutral'.

Detailed Analysis

It helps to group the seven charts into three stories: the growth engine, the living-standards squeeze, and the fiscal vice. Each cluster explains a different reason why Burnham's task is genuinely difficult, and why the easy answers have mostly been tried before. The point of reading them together is that progress on one front is usually constrained by the others.

The growth engine: productivity and business investment

The first two charts describe the supply side of the economy. The productivity line — output per hour worked — is the one economists watch most closely. For decades it climbed at a fairly steady rate; since the 2008 financial crisis it has grown far more slowly, a slowdown so persistent that the Office for Budget Responsibility has repeatedly had to trim its long-run assumptions. The illustrative shape is a curve that flattens sharply after 2008 and never fully recovers its old trajectory.

That flattening is the single most important fact in British economic policy, because productivity growth is what ultimately pays for higher living standards. If workers produce more each hour, employers can pay more without raising prices, and the government can collect more tax without raising rates. When the line goes flat, the country ends up arguing over how to share a pie that is barely growing.

The business-investment chart helps explain why. On this measure the UK has sat near the bottom of the G7 as a share of GDP for years, a pattern documented by bodies such as the ONS and flagged by think-tanks including the IPPR. Firms that invest less in machinery, software, research and training tend, over time, to raise output per worker more slowly. Weak investment and weak productivity are two views of the same underlying reluctance to commit capital.

For Burnham this is both the problem and the opportunity. He has been urged to use fiscal-rule flexibility to lift public investment — potentially freeing up to £16bn for infrastructure over the rest of the decade — on the theory that better transport, energy and digital networks would crowd in private money rather than crowd it out. The counter-argument, made in the FT's own commentary, is that the state cannot substitute for private confidence; it can only try to create the conditions for it.

The living-standards squeeze: real wages, regional gaps and energy

The next three charts describe how the growth problem is felt by households and places. The real-wage chart is the bluntest. Adjusted for inflation, average pay has barely risen across the years since the financial crisis — a stretch of near-stagnation with few parallels in modern British history. This is the chart that sits behind kitchen-table politics, and behind Burnham's decision to lead with affordability and to redirect money from the scrapped digital ID scheme towards cost-of-living priorities.

The regional chart adds a geographic dimension. Output per person in London stands well above that of most other parts of the country, and the gap has proved stubborn despite successive rebalancing programmes, from regional development agencies to the 'Northern Powerhouse' and 'levelling up'. The illustrative bar chart shows the capital and its surroundings clustered at the top, with much of the North, the Midlands and the coast strung out below the national average.

Commentators have refined this picture in ways Burnham will need to absorb. Alison McGovern has argued that the true divide is 'insiders versus outsiders' rather than simply north versus south, because growth that clusters in regional hotspots can still leave nearby towns such as Hartlepool behind. The challenge is to lift the places on the periphery of prosperity, not only the big cities.

The energy chart ties the regional and investment stories together. UK industrial electricity prices rank among the highest in the developed world, a burden that falls hardest on the energy-intensive manufacturing often concentrated outside the South East — steel among them. High power costs discourage exactly the kind of investment that would raise regional productivity, and the energy-price effects of the Iran war have pushed the issue back up the agenda. Foreign Secretary Ed Miliband's earlier drive to decarbonise electricity was framed, in part, as a long-run answer to precisely this chart.

The fiscal vice: gilt yields and public debt

The final two charts explain why Burnham cannot simply spend his way past the first five. The gilt-yield chart shows the interest rate the government pays to borrow rising well above the near-zero levels that prevailed for much of the 2010s. Around the handover, gilts came under fresh pressure as investors braced for higher spending under the new prime minister, and Burnham's promise to 'use any flexibility' in the fiscal rules did nothing to calm those nerves.

Higher yields matter because they raise the cost of servicing the national debt, diverting money that could otherwise fund services or investment. When markets doubt a government's fiscal discipline, they demand a higher return to hold its bonds, which tightens the very constraint the government is trying to loosen.

The public-debt chart sets the backdrop. Net debt sits close to 100 per cent of GDP, around its highest level since the early 1960s, after the combined costs of the financial crisis, the pandemic and the energy emergency. A debt stock that large leaves little headroom for shocks and makes the economy more sensitive to each move in interest rates. The illustrative line climbs steadily across two decades and refuses to come down.

This is where the external warnings bite. The IMF has said Britain cannot afford an unfunded spending surge; the economist Martin Wolf has cautioned that the biggest mistake a new government can make is to imagine there is a 'free fiscal lunch'; and the Treasury's own numbers show a near-£5bn gap in the previous government's defence-spending plan that Burnham and his chancellor, John Healey, must close. These fiscal charts are the reason the other five cannot be fixed with money alone, and why the choices ahead are genuinely hard rather than a matter of will.

What Happens Next

The first thing to watch is how Burnham translates his growth rhetoric into a plan that respects the fiscal charts. His early signals on investment — whether he leans on the flexibility that could free up to £16bn for infrastructure, and where he directs it — will tell markets a great deal about how he reads the trade-off between growth and gilt yields. Front-loading investment could lift the productivity line over time, but at the risk of testing already nervous bond investors.

The autumn Budget will be the first formal test. That is when Healey, the surprise choice as chancellor, must show how the government intends to raise investment and productivity without breaching its rules or spooking lenders. The near-£5bn defence gap, the IMF's insistence on 'targeted, temporary and budget-neutral' measures, and Burnham's cost-of-living promises will all have to be reconciled in a single set of numbers.

On the regional charts, expect early attention to devolution and to the terms on which power and money flow to mayors and combined authorities. This is Burnham's home ground, and lenders such as NatWest and Lloyds have signalled a willingness to help finance regional growth. The measure of success will be whether investment reaches beyond the strongest cities to the peripheral towns that McGovern's 'insiders versus outsiders' framing highlights.

With industrial power costs high and the Iran war keeping prices elevated, pressure will build on the government to show a credible route to cheaper, more secure electricity. How Burnham balances that against his commitment to maintain the ban on new North Sea exploration licences will be one of the defining tensions of his first year.

Conclusion

The value of reading these seven charts side by side is that they turn a vague sense of national decline into a set of specific, measurable weaknesses. Weak productivity and investment explain why the economy grows slowly; wide regional gaps, stagnant real wages and expensive energy explain why that slow growth feels so unfair; and high gilt yields and public debt explain why the obvious remedies are so constrained. None of them is new to Burnham, and none has an easy fix.

That is precisely why his premiership is a genuine test rather than a formality. The charts do not tell him what to do, but they rule out the comforting illusion that Britain's problems can be solved by announcements or by borrowing alone.

Burnham has framed his arrival as the most significant moment in British politics for 40 years. Whether it becomes a turning point for the economy will depend on how honestly his government engages with these charts — and on its willingness to make the hard, unglamorous choices that each of them, quietly, demands.
