Former Bank of England governor Mark Carney has criticised the new British government's plan to cut taxes for undercutting efforts by the central bank to curb inflation and for sowing chaos in financial markets.

"Unfortunately having a partial budget, in these circumstances - tough global economy, tough financial market position, working at cross-purposes with the Bank - has led to quite dramatic moves in financial markets as we have all seen," Carney told the BBC in an interview broadcast today.

Last week, finance minister Kwasi Kwarteng followed through on Prime Minister Liz Truss's promises of tax cuts by announcing further reductions in taxation without detailing the impact on the public finances or explaining his economic growth plans.

The pound sank and British government bond yields soared, forcing the Bank of England to revive its bond-buying in an emergency move on Wednesday to shore up pension funds.

Carney said the government was right to focus on getting Britain's economy to grow more quickly but that ambition remained for the future and in the short term there was confusion about how the public finances were going to add up.

The lack of an assessment by Britain's budget watchdog, the Office for Budget Responsibility, was a concern for investors, the Canadian who ran the Bank of England until 2020 said.

"It's important to have (the budget) subject to independent and dare I say expert scrutiny," Carney said.
