UK finance minister faces £36bn budget gap, think tank warns
UK Finance Minister John Healey is preparing his first budget, due on October 28.
The Institute for Fiscal Studies says he needs to find £36 billion through tax increases or cuts to welfare spending just to cover inflation’s effect on public services and meet defence spending commitments.
Inflation has risen amid the war with Iran, making the government’s existing budget plans harder to meet.
Healey and Prime Minister Andy Burnham have promised to ease living costs and keep the basic rates of income tax unchanged, while facing pressure to raise defence spending to 3% of national output.
The think tank estimates inflation will average 3.1% this year and 3% in 2027, above earlier official forecasts.
The government could delay major changes until a spending review in 2027, but the institute warns investors may not accept a plan based mainly on hoping borrowing costs fall.
The budget will set out Healey’s choices, while the institute says the government’s available financial headroom could be about £20 billion in 2029-30.
The Institute for Fiscal Studies says UK finance minister John Healey will need to find £36 billion through tax rises or welfare spending cuts in his first budget.
The institute says the money would cover inflation’s effect on public services and meet defence spending commitments.
The budget is due on 28 October, and the institute warns that keeping existing plans unchanged is no longer realistic.
The government has pledged not to raise basic tax rates, while facing pressure to contain welfare costs and set a timetable for higher defence spending.
The institute estimates the government’s financial headroom in 2029-30 could be about £20 billion, down from a previous estimate of £24 billion.
