Conservatives accused Labour of โ€œtapping the nationโ€™s credit card while the bailiffs are at the doorโ€ as new figures showed national debt had reached nearly ยฃ3 trillion. The Government is spending nearly ยฃ7.7 billion every month just on interest – more than it spends on defence, police and prisons combined. Chancellor John Healey insisted the Government was cutting the deficit, saying: โ€œFiscal discipline is the bedrock of our UK economic stability and national security.โ€

But experts warned Mr Healey and Prime Minister Andy Burnham would be forced to increase taxes in the Budget on October 28 to avoid debt increasing even faster. New figures from the Office for National Statistics (ONS) showed government borrowing unexpectedly rose to ยฃ1.8 billion last month, ยฃ700 million than a year previously. Itโ€™s a blow because official spending watchdog the Office for Budget Responsibility had predicted a ยฃ500 million surplus. The borrowing hike also came even though more income tax than ever before has been collected.

Total UK debt is now just shy of the ยฃ3 trillion key milestone, at a mammoth ยฃ2.985 trillion, or 94.1% of gross domestic product (GDP).

Sir Mel said: โ€œThe ONS has confirmed the national debt is now almost ยฃ3 trillion. That is over ยฃ100,000 of debt for every single household in Britain. And we are all paying for it, every day. We spend more on just the interest of our soaring debt than we do on our defence, police, and prisons combined.

โ€œWe simply cannot afford the price of Labour. They already plan to borrow over a quarter of a trillion pounds more than the plans they inherited. It is ordinary families, their children and grandchildren who are left to cover the bill.

โ€œOnly the Conservatives have a credible plan to get the national debt down with ยฃ50 billion in spending cuts, starting with the welfare bill.โ€

Income tax receipts hit ยฃ17.1 billion last month โ€“ up ยฃ1.7 billion on a year ago, according to the ONS.

But spending outweighed the tax boost, with another ยฃ2 billion spent on social benefits compared with a year ago, while the interest on government debt payments also rose by ยฃ700 million, to ยฃ7.7 billion last month.

Thomas Pugh, chief economist at RSM UK, said tax rises would be needed to allow the Government to stick to fiscal rules designed to limit borrowing.

He said: โ€œThe commitment to sticking to the fiscal rules means further tax rises are inevitable come the autumn Budget.

โ€œThe risk is that more borrowing to spend fuels inflation and pushes up gilt yields further, leaving the new Chancellor having to borrow more just to stand still.โ€

The figures come days after Prime Minister Andy Burnham said the new Manchester-based satellite office of Downing Street will take over responsibility for growth, while the Treasury will focus on controlling the public finances.

Grant Fitzner, chief economist at the ONS, said: โ€œBorrowing was slightly higher this month than in July last year, with spending growth outpacing higher receipts, including from self-assessed taxes which often feed in more strongly in July.โ€
