UK: British minister Penny Mordaunt announces bid to be next PM

British minister Penny Mordaunt on Friday launched her bid to replace Liz Truss as prime minister, becoming the first Conservative lawmaker to announce they are running.

Mordaunt, 49, has navigated the tenures of the four prime ministers she has served under, keeping her distance from Boris Johnson's scandal-ridden time in power and staying in cabinet under Theresa May to make her support for Brexit felt.

This is the second time she is running for the top job, after just missing out on the final two in the contest to become the leader of the ruling Conservative Party earlier this year. That race saw Truss defeat former finance minister Rishi Sunak.

"I'm running to be the leader of the Conservative Party and your Prime Minister - to unite our country, deliver our pledges and win the next GE (General Election)," Mordaunt said on Twitter.

"I've been encouraged by support from colleagues who want a fresh start, a united party and leadership in the national interest."

Bookmakers place Mordaunt third, behind Sunak and Johnson, who are also expected to enter the race to succeed Truss.

Under Truss, she was appointed leader of the House of Commons, a role which also by chance gave her a higher profile job as "Lord President of the Privy Council" - meaning she presided over the formal announcement of Queen Elizabeth's death and the proclamation of the new King Charles.

Largely unknown outside Westminster prior to taking an early opinion poll lead among Conservative Party members earlier this year, some of the public may have first seen Mordaunt on the reality TV show Splash! in 2014, where celebrities learnt to dive. She performed a belly flop.
