British Prime Minister Liz Truss on Monday apologized for her controversial mini-budget that crashed the country’s currency, rattled financial markets and led to her firing her finance minister and closest political ally.

In an exclusive interview with the BBC, Truss insisted she would lead her Conservative Party into the next general election, despite her government being under huge pressure from investors and party members since the mini-budget was unveiled in late September.

The plan – which proposed unfunded tax cuts, huge government borrowing and exempted energy companies from a windfall tax – sent the pound tumbling to its lowest level against the dollar in decades.

“I do want to accept responsibility and say sorry for the mistakes that have been made. I wanted to act to help people with their energy bills to deal with the issue of high taxes, but we went too far and too fast,” Truss told the BBC’s Chris Mason.

“I put in place a new chancellor with a new strategy to restore economic stability.”
