We argued in March that Andy Burnham’s premiership would be judged on whether new public investment shows up in growth data before the next election. Tuesday’s unrevised 0.3% second-quarter GDP print offers little evidence that the bet is paying off yet.
Numbers that refuse to budge
The Office for National Statistics left Q2 growth unchanged at 0.3%, with a wider trade deficit offsetting modest service-sector strength. Manufacturing continued to contract, and business investment was flat after adjusting for inflation.
That matters because the Treasury is preparing an autumn statement built on higher capital budgets for grid upgrades and NHS estates. Without productivity gains, each pound of borrowing buys less relief than ministers imply in conference speeches.
Fiscal room is narrower than the rhetoric
Chancellor Rachel Reeves—still setting the tax baseline Burnham inherited—has only limited headroom under self-imposed rules if growth forecasts stay near 1% for 2026. Markets already price gilt issuance above pre-election paths.
What government should do now
First, publish the full OBR scenario that underpins grid and care-service pledges, including sensitivity to higher gilt yields. Second, tie major project approvals to measurable commissioning dates, not ribbon-cutting targets. Third, keep Bank of England independence out of political messaging; hinting at rate cuts to fund spending would spook the very investors Labour says it wants in UK assets.
Burnham’s team can still argue structural reforms take time. True—but voters heard that in 2024. Another quarter of 0.3% growth is not a mandate for unrestrained borrowing; it is a warning to sequence promises honestly before the autumn statement.
Investment without absorption
Public investment can crowd in private capital when grids and housing pipelines are credible. Yet Tuesday’s data show construction flat and manufacturing shrinking—signs that money is not yet moving dirt at scale. Without faster planning decisions and skilled-worker visas for electricians, grid rhetoric will outrun delivery.
We supported targeted capital spending when Labour took office; we still do. The difference is that another year of subdued growth demands honesty about trade-offs, not another round of slogans about fixing public services without saying who pays.
Markets will forgive a government that misses one growth target if credibility on fiscal rules remains intact. They will not forgive surprise tax grabs dressed up as technical adjustments.
