Kemi Badenoch roasted 'people-pleaser' Andy Burnham over his refusal to curb benefits today - as he faces a mounting markets crisis.The Tory leader accused Mr Burnham of failing to turn down any spending demands from his own Labour MPs.In his first PMQs, she warned investors were clearly 'worried' as interest rates increase on the Government's debt mountain.Mrs Badenoch branded Mr Burnham a 'spendthrift' premier who 'wants to say yes to everyone'. 'I think it's delightful that he wants to make everyone happy. But a prime minister needs to be a leader, not a people pleaser,' she jibed.The PM again refused to rule out tax rises at the Budget next month - but insisted he did want the welfare bill to fall. Even allies were dismayed by Mr Burnham's blustering debut in the House yesterday, where he blamed Brexit and even Thatcher for Britain's problems but offered little policy substance.Long-term supporter Jim O'Neill, a former minister and Goldman Sachs economist who recently turned down a job advising the PM, warned that mortgage rates could soar as the UK is punished for the lack of a 'sensible fiscal strategy'.He insisted Mr Burnham must 'get real' on issues such as welfare and state pensions and his speech had been the 'last thing' markets wanted to hear. Lord O'Neill told LBC: 'If your country is under the focus of ''can they come up with a sensible fiscal strategy'' on a day when the markets think ''well no, you're not showing any sign of it'' you're going to have a tough day… if it stays like this your mortgage rate is going up.' Interest rates on gilts - one of the main ways the Government borrows money - rose during Mr Burnham's statement, having hit multi-decade highs during the day. They continued to climb this morning. The flare-up in the Iran war, persistent inflation, and nerves about a potential AI correction have been pushing up the costs of state debt around the world, but the UK is seen as particularly vulnerable.
