Chancellor John Healey faces additional pressure after the British government’s monthly deficit climbed in August. Public sector net borrowing hit £18.3 billion, surpassing the £15.5 billion estimate and the £1.8 billion recorded in July. This latest figure contributes to a trend of borrowing exceeding forecasts through the first five months of the current fiscal year.

The Labour government is considering a proposal from Keir Starmer's previous tenure to exclude borrowing for building projects from existing fiscal rules. Such an adjustment would allow the administration to finance infrastructure and construction projects without those expenditures impacting official deficit targets.
