Sir Keir Starmer has said Liz Truss is “not on the side of working people” after she was unveiled as the new leader of the Conservative party.

Truss beat out rival Rishi Sunak by 81,326 votes to 60,399 after the vote was put to the Tory membership.

In her victory speech Truss said: “Thank you for putting your faith in me to lead our great Conservative Party, the greatest political party on earth.

“I know that our beliefs resonate with the British people: our beliefs in freedom, in the ability to control your own life, in low taxes, in personal responsibility.

“I know that’s why people voted for us in such numbers in 2019 and as your party leader I intend to deliver what we promised those voters right across our great country.”

Giving his reaction to the result of the leadership election at Friern Barnet School in north London, Starmer told journalists: “We’ve heard far more from the latest prime minister about cuts to corporation tax over the summer than we have about the cost-of-living crisis, the single most important thing that’s bearing down on so many millions of households.

“That shows not only that she’s out of touch, but she’s not on the side of working people. So she needs to deal with the cost-of-living crisis, she needs to deal with the fact the NHS is on its knees, and she needs to deal with the collapse of law and order.

“There can be no justification for not freezing energy prices. There’s a political consensus that needs to happen. She needs to ask the question how she’s going to pay for that. Labour made it clear, it needs to be a windfall tax on oil and gas companies.

“So, she needs to show that she actually understands and can meet the challenges that are there after 12 years of failure of this Tory Government.”
