British Prime Minister Liz Truss continues to refuse to step down despite the failure of her tax policy.
"I'm a fighter, not a slacker," Truss said at Wednesday's weekly Question Time session in the House of Commons in London.
The conservative head of government came under heavy pressure at the meeting.
Several opposition politicians called on her directly to step down.
Only on Monday did Treasury Secretary Jeremy Hunt withdraw almost all parts of Truss' recently announced radical tax cuts.
The plans presented without counter-financing had led to severe turbulence on the financial markets.
Truss countered allegations that she had driven the country's economy to the wall by stating that the economic situation was generally difficult.
For this, she earned angry heckling from the opposition benches.
The head of government, who had gotten heavily on the defensive, was spared criticism from within her own ranks.
Speculations that she could have bought the loyalty of the Brexit hardliners with a hard line towards Brussels in the dispute over the status of Northern Ireland seemed to be confirmed.
When asked by a member of parliament, Truss assured that she wanted to stick to a bill that would undermine the agreement known as the Northern Ireland Protocol from the Brexit Treaty.
