Andy Burnham refused to rule out Budget tax rises in a PMQs grilling by Kemi Badenoch. The Tory leader urged the Prime Minister to “be honest and tell us” if he planned to hike taxes next month during the Commons clash amid soaring government borrowing costs.

She said: โ€œThe markets are clearly worried that we now have a spendthrift Prime Minister who wants to say yes to everyone but cannot tell us where the money is coming from. He needs to pay for all his new promises, and he has a choice: higher taxes, more borrowing or spending cuts.

โ€œYesterday, he said change begins with honesty. So, will he be honest and tell us? Is he preparing to raise taxes again? Yes or no?โ€

But Mr Burnham insisted he is not going to โ€œwrite the Budgetโ€ at the despatch box.

He said: โ€œIโ€™ve already indicated my first moves were to cut tax, but Iโ€™m not going to do what any prime minister has done and write the Budget here. That will be the matter for my Right Honourable friend (Chancellor John Healey).

โ€œBut can I also say to her that he and I took a deliberate decision to set an early date for the Budget so that we reduce the period for prolonged speculation of the kind that she is wanting us to indulge in today.โ€

Mr Burnham had already declined to rule out tax rises in the Budget yesterday when he made his first statement to the Commons as PM.

Mrs Badenoch also challenged Mr Burnham over criticism by his ally Lord O’Neill after he set out his plans for Government.

She said: โ€œLord Oโ€™Neill, a close friend of the Prime Minister, said yesterdayโ€™s statement in the Commons was the last thing investors wanted to hear.

โ€œLord Oโ€™Neill is a serious economist. He knows what heโ€™s talking about, and sure enough, yesterday the cost of Government borrowing rose to its highest in 18 years. How does he plan to tackle the Governmentโ€™s rising debt costs?โ€

Mr Burnham replied: โ€œIโ€™ve worked with Jim Oโ€™Neill for 10 years. Jim Oโ€™Neill always gives me candid advice.

โ€œWe donโ€™t always agree, but he and I worked together to turn Greater Manchester from a former industrial heartland to the fastest-growing city region in the country.โ€

Government long-term borrowing costs have been sent soaring to their highest levels for 28 years, amid a global bond sell-off partly linked to signs of escalation in the Middle East conflict and the concern that inflation could follow.
