Rishi Sunak, who yesterday became leader of the Conservative Party, will officially become Britain’s third Prime Minister in 50 days this morning after meeting King Charles III.

Former Prime Minister Liz Truss will make a short speech outside Downing Street at around 10.15pm before visiting Buckingham Palace herself. She will be quickly followed by Mr Sunak, who is expected to appear outside the doors of Number 10 shortly before 12pm.

Mr. Sunak will then proceed to appoint his new cabinet. This new cabinet is likely to mark the end of the ministerial careers of a number of familiar faces, such as business secretary Jacob Rees-Mogg and Welsh minister Robert Buckland.

Mr. Sunak is expected to appoint a number of his key supporters to cabinet posts instead. These include Dominic Raab, Oliver Dowden and Mel Stride – all former ministers. The trio were highly visible on air campaigning for Mr Sunak during the Conservative leadership election this summer.

Given that he has not committed to spending 3% of GDP on defense, attention will soon turn to appointing a defense minister. The current president, Ben Wallace, is very popular among members of the Conservative Party. However, he noted that any failure to meet the 3% target would mean resignation, something Mr. Sunak has always refused to do.

Over the past 46 years, around 7 out of the last 10 UK Prime Ministers have entered Downing Street following an election or an intra-party leadership contest. Only three, David Cameron, Tony Blair and Margaret Thatcher, have taken the reins of power after a public vote in a general election. The Labor Party has now called on Mr Sunak to win his own mandate by calling a general election.

42-year-old Sunak will become the second youngest Prime Minister of Great Britain. He is a year younger than Tony Blair and David Cameron, who entered Downing Street at the age of 43.

Only William Pitt the Younger, who became prime minister aged 24 in 1783, was younger than Mr Sunack.

Mr Sunak will also become the first non-white Prime Minister.

Mr. Sunak is 57 years oldthousand man will serve as prime minister, succeeding 47-year-old Liz Truss, who will soon have the honor of being the shortest-ever prime minister.
