British Prime Minister Liz Truss has triggered a new row in her party by suggesting she could limit increases in benefit payments by less than rising inflation, as she seeks ways to fund her tax-cutting growth plan.
Britain's new leader has endured a tumultuous time since she came to power early last month, first leading mourning for Queen Elizabeth before releasing an economic package that immediately roiled financial markets.
Seeking to snap Britain out of more than 10 years of economic stagnation, Ms Truss and her finance minister Kwasi Kwarteng set out £45 billion of unfunded tax cuts on 23 September, alongside promises to deregulate the economy to stoke growth.
They bowed to pressure yesterday to scrap the most divisive policy - eliminating the top rate of income tax for the highest earners - and are now working urgently to set out how they can afford the other tax cuts without leaving a huge black hole in the country's public finances.
"We have to look at these issues in the round. We have to be fiscally responsible," Ms Truss told BBC Radio when asked whether benefit payments would rise in line with record-high inflation to prevent the poorest in society from becoming poorer.
Immediately Conservative Party MPs - some who helped force the top tax rate reversal - opposed any move to reduce the increases in benefits at a time when millions are struggling with higher costs of food and energy.
Penny Mordaunt, who is in Ms Truss's cabinet of senior ministers, said benefits should rise in line with inflation. Damian Green, part of the party's centrist faction, said he doubted any real-terms cut would pass a parliamentary vote.
"I think there will be many of my colleagues who think that when you're reaching for spending cuts, benefit payments are not the way to do it," Mr Green told BBC Radio. Another MP, Roger Gale, also signalled his opposition.
Victoria Prentis, a minister in the Department for Work and Pensions, told Reuters the government had to go through the numbers before it could take a final decision on benefits.
British interior minister Suella Braverman accused certain sections of the party of staging "a coup effectively" over the top tax rate cut.
"I am very disappointed to say the least about how some of my colleagues have behaved," she said, at the party's annual conference.
Ms Braverman also said when she ran for leader of the party she "was actually quite clear ... that I wanted to cut welfare spending," adding she supported the cut to the top rate of tax.
Mr Kwarteng has set 23 November as the date for his next fiscal statement. A government source said the Treasury was considering bringing that forward but any change would most probably be announced once parliament resumes next week.
Ms Truss became Britain's fourth leader in six years last month, promising to reignite the economy and bring some political stability after the chaotic leadership of Boris Johnson.
Chosen by her party's members, not the broader electorate, she was not the most popular candidate among the more than 350 Conservative members of parliament and her decision to stake out a tax cut plan and then concede defeat has left MPs and investors questioning her judgement and authority.
At the annual conference in Birmingham, some politicians and commentators have questioned whether she has a mandate to take Britain back to a 1980s-style Reagonomics policy without a national election.
The Conservatives won the 2019 election with Mr Johnson promising to increase spending on public services.
"It is not a great thing to sell the public on one type of package and vision, and then completely flip it and appear not to care," Rachel Wolf, the co-author of the Conservatives 2019 manifesto, said on Sunday.
Investors have also taken fright at the new economic policy direction, hammering the value of British assets so hard that the Bank of England had to intervene last week with a package worth up to £65 billion to shore up the bond market.
Mortgage costs have already risen.
Mohamed El-Erian, an adviser to financial services giant Allianz, said the government needed to get its house in order. "We are not a developing country and we need to stop acting like a developing country," he told Sky News.
The Bank of England action has calmed markets for now, while investors also took some comfort from the tax U-turn and the hoped-for move to bring forward the publishing date for the next fiscal plan from 23 November.
But Boris Glass, senior economist at S&P Global ratings agency, said Britain faced a difficult winter.
"Unless strong medium-term growth can fully fund the extra spending, medium-term fiscal tightening appears inevitable, which may weigh on future growth," he said.
