UK government borrowing rose by more than expected to ยฃ24.5 billion for last month, underscoring the constraints in the public finances ahead of the Chancellorโ€™s Budget next week.

The Office for National Statistics (ONS) reported that public sector net borrowing increased by ยฃ1.8 billion compared with the same month last year.

It was also ยฃ1.9 billion ahead of Office for Budget Responsibility (OBR) forecasts, and above the ยฃ24.1 billion widely predicted by economists.

It comes only a week ahead of Chancellor John Healeyโ€™s first Budget, where he is expected to increase bank taxes as higher borrowing costs weigh down on fiscal headroom.

ONS chief economist Grant Fitzner said: โ€œBorrowing in the first six months of the current financial year remained below the same period last year, thanks to higher receipts, although it was still above the official forecast.

โ€œPreliminary figures suggest that although debt in cash terms continues to rise, as a proportion of GDP it has fallen over the year.

โ€œOn this latter basis it remains at levels last seen in the early 1960s.โ€
