Will Rishi Sunak be next Prime Minister of Britain?

Rishi Sunak looked set to become next Prime Minister of Britain after Boris Johnson withdrew from the contest on Sunday. Although he enjoys enough support to make the final ballot he realizes the country and the Conservative Party needed unity.

If chosen, Sunak would be the first prime minister of Indian origin in the United Kingdom.

Johnson had raced home from a holiday in the Caribbean to try and secure the backing of 100 lawmakers to enter Monday's contest to replace Liz Truss, the woman who succeeded him in September after he was forced to quit over a string of scandals.

He said he had secured the backing of 102 lawmakers and could have been "back in Downing Street", but that he had failed to persuade either Sunak, or the other contender Penny Mordaunt, to come together "in the national interest".

"I believe I have much to offer but I am afraid that this is simply not the right time," Johnson said late on Sunday.

The former prime minister had secured the public backing of just under 60 Conservative lawmakers by Sunday, well under half of the nearly 150 endorsements Sunak had received.

Johnson's statement likely paves the way for his arch rival, the 42-year-old former finance minister Sunak, to become prime minister, possibly as soon as Monday. If confirmed, he would replace Truss who was forced to resign after she launched an economic program that triggered turmoil on financial markets.

According to the rules, if only one candidate secures the backing of 100 Conservative lawmakers, they will be named prime minister on Monday.

If two candidates pass the threshold, they will go forward to a vote of the party membership, with the winner announced on Friday, just days before new finance minister Jeremy Hunt lays bare the state of the country's finances in a budget plan due to be released on October 31, 2022.

That had raised concerns that Johnson would return to Downing Street with the backing of the party members, and not a majority of lawmakers in parliament, leaving the party badly divided. Hunt declared his backing for Sunak late on Sunday.

Some Johnson supporters could switch to Mordaunt, who has presented herself as the unity candidate, but many immediately switched to Sunak. A source close to the Mordaunt campaign said the former defence minister would continue in the contest.

"She is the unifying candidate who is most likely to keep the wings of the Conservative Party together," the source said.

Johnson has loomed large over British politics ever since he became mayor of London in 2008 and went on to become the face of the Brexit vote in 2016. While he led the Conservative Party to a landslide election in 2019, he was forced out just three years later by a rebellion of his ministers.

Sunak said he hoped Johnson would continue to contribute to public life "at home and abroad".

One Sunak supporter, who asked not to be named, said his main reaction was relief because if Johnson had won the "party would have torn itself apart".

Another Conservative lawmaker Lucy Allan said on Twitter: "I backed Boris for PM, but I think he has done the right thing for the country."

Other Johnson backers immediately jumped ship.

Cabinet office minister Nadhim Zahawi, who minutes earlier had published an article on the Daily Telegraph website praising Johnson, said "a day is a long time in politics".

"Rishi is immensely talented, will command a strong majority in the parliamentary Conservative Party, and will have my full support and loyalty," he said.

Earlier, many of the Conservative lawmakers who normally back Johnson switched their support to Sunak, saying the country needed a period of stability after months of turmoil that has sparked headlines - and raised alarm - around the world.

Johnson is also still facing a privileges committee investigation into whether he misled parliament over Downing Street parties during COVID-19 lockdowns. He could be forced to resign or be suspended from office if found guilty.

Sunak first came to national attention when, aged 39, he became finance minister under Johnson just as the COVID-19 pandemic arrived in Britain, developing a furlough scheme to support millions of people through multiple lockdowns.

"I served as your chancellor, helping to steer our economy through the toughest of times," Sunak said in a statement on Sunday. "The challenges we face now are even greater. But the opportunities - if we make the right choice - are phenomenal."

His family migrated to Britain in the 1960s, a period when many people from Britain's former colonies arrived to help rebuild the country after the Second World War.

After graduating from Oxford University, he later went to Stanford University where he met his wife Akshata Murthy, whose father is Indian billionaire N. R. Narayana Murthy, founder of outsourcing giant Infosys Ltd.
