London, October 22: Merely three months after he was ousted from power, former British Prime Minister Boris Johnson landed in Britain on Saturday from a Caribbean holiday to launch a formal bid for the Conservative Party leadership, following Liz Truss's resignation this week, according to UK media reports.

Johnson was forced to step down on July 7 following a series of resignations of cabinet members, who protested against his scandal-plagued leadership. Johnson now expressed his willingness to enter the PM race, saying he is "up for it."

Former Chancellor of the Exchequer Rishi Sunak in the Johnson cabinet was also quick to mark his bid for the Tory and the British Prime Ministership having secured more than a hundred nominations - which is the minimum requirement to contest for the post. UK Political Crisis: Priti Patel Endorses Boris Johnson As New British PM to Replace Liz Truss.

Sunak late Friday became the first Tory leadership contender to reach the 100-nomination threshold to run for party leader following the resignation of Prime Minister Liz Truss, reported Independent citing campaign sources.

Sunak, who fell to Truss in the last leadership contest, got the backing of at least 100 Conservative Party lawmakers to enter the UK PM race.

This is a key development after Liz Truss' resignation as UK Prime Minister on Thursday which threw the country into political turmoil and left it scrambling for a stable government, as the opposition reiterated its demand for a general election.

On Friday, Penny Mordaunt, the Tory leader in the House of Commons too threw her hat in the ring. "I've been encouraged by support from colleagues who want a fresh start, a united party and leadership in the national interest," Mordaunt tweeted. Tory MPs will vote on Monday, and two candidates will be put forward to the Tory membership unless one pulls out. The result will be announced on Friday, October 28.

It is pertinent to note that Truss became the shortest-serving British PM after she stepped down, stating that she recognises she "cannot deliver the mandate" on which she was elected. Truss said she would step aside for a new leader to be chosen within the next week. UK PM Race: Boris Johnson Gets Backing Of More Than 100 Tory MPs, His Campaign Claims.

In view of Truss's resignation, Labour Party leader Keir Starmer issued a scathing statement that ripped into the Conservative Party and called for a general election. After 12 years of "Tory failure," he said the British people deserve so much better than this revolving door of chaos. "We need a general election now," he said.

Truss stepping down was preceded by the sacking of UK Finance Minister Kwasi Kwarteng and the resignation of Home Secretary Suella Braverman tendered her resignation. Liz only remained in power for 45 days after succeeding Boris Johnson last month.
