Rachel Reeves has vowed "I'm not going to let them get me down" as she fought back against her critics over Labour's economic turmoil.
Speaking to the BBC's Political Thinking podcast, the chancellor who's come under fire over rising borrowing costs said she was in her job for the "long haul".
Reeves said the rise was "not a British phenomenon" and that other countries had also seen borrowing costs increase.
She also insisted she has "got what it takes to deliver for people in this country" and the ideas to "turn things around".
Her comments came after the British economy had grown by 0.1% in the last three months, adding concern that growth could remain stagnant for some time.
The Conservatives have accused the chancellor of "burying her head in the sand" and called for an "urgent change of course".
Ms Reeves admitted that current levels of growth were "not good enough" and that boosting figures was the "number one mission of the Labour government", and that she would be meeting regulators to encourage them to "do what is needed" to boost growth.
"We are not going to be able to grow the economy if the regulators keep doing what they're doing," she added.
