Liberal Democrat Cabinet Office spokeswoman Christine Jardine called on Prime Minister Rishi Sunak to “do the right thing and stop Liz Truss from claiming taxpayers’ money from the former prime minister’s fund”.
“It is a scandal that Liz Truss is profiting from her own failures while families struggle to pay their bills and put food on the table,” she said.

Sir Tony Blair and Sir John Major were the only former frontrunners to claim the top amount in 2022/23, although Gordon Brown was close with £114,627.
Her office declined to comment.
