Sunak won 118 votes on Tuesday,
the gloves came off.
Liz Truss will not be able to win a general election and would put MPs’ seats at risk,” a Mordaunt aide said.
Mordaunt’s campaign claimed that foreign secretary Liz Truss could not win a general election and that if she became prime minister Tory MPs risked losing their seats.
After Wednesday’s vote, about 150,000 Conservative activists will vote on which of the two candidates they want to be their party leader and prime minister, with a result declared on September 5.
Mordaunt herself retweeted a Daily Telegraph column by Allison Pearson with the headline: “Vote for Rishi Sunak or Liz Truss today and you’ll murder the party you love.”
