LONDON, June 19 - Britain recorded a budget deficit of £23.3 billion in May, the Office for National Statistics said on Friday. The shortfall marked a 30% increase compared with the same month a year earlier and exceeded the median forecast of economists polled, who had expected a deficit of £18.5 billion for May.
Earlier this year, in March, the government's independent budget watchdog projected a deficit of £115.5 billion for the 2026/27 financial year. That estimate equated to 3.6% of national income, a decline from the 4.3% recorded in 2025/26. Since that March projection, the outlook for economic growth has weakened and the cost of borrowing has risen, developments that have altered the fiscal backdrop.
The market reaction to the rising cost of debt has been evident in recent gilt auctions. Last week the government sold £9 billion of 15-year debt at yields described as the highest since at least 1998, reflecting tighter financing conditions for public borrowing.
Beyond the numerical outcomes, fiscal management faces political and budgetary strain. The government is reported to be struggling to accommodate additional defence spending within current budget rules and pre-existing commitments to other departments. That tension culminated in the resignation of defence minister John Healey last week, who stepped down in protest over the handling of defence funding.

Context and implications
The larger-than-expected May deficit, the downgraded growth outlook and higher borrowing costs combine to create a more challenging fiscal environment than was envisioned in the March projection. The recent gilt sale at elevated yields underscores pressure in debt markets. Separately, the difficulty of financing additional defence commitments within existing fiscal rules has produced a notable political repercussion.
