Rishi Sunak has been formally appointed prime minister, having met King Charles at Buckingham Palace.
At 42, Sunak is the youngest UK prime minister in over 200 years. He is also both the country’s first British Asian and first Hindu leader.
He takes over following months of chaos within the Conservative Party which saw the downfall of Boris Johnson and the short but chaotic tenure of Liz Truss.
His predecessor’s swiftly abandoned agenda of borrowing and tax cuts spooked the markets and tanked the party’s poll ratings.
Speaking in Downing Street shortly after assuming office, Sunak said he would “fix” the “mistakes” made by Truss.
And he warned country was facing a “profound economic crisis”.
Sunak’s first job will be to appoint a new cabinet, before facing Labour leader Keir Starmer at PMQs on Wednesday.
Long-time backers Dominic Raab, the former justice secretary, Commons Treasury Committee chairman Mel Stride and ex-chief whip Mark Harper have been tipped for jobs.
While not confirmed, Jeremy Hunt, who replaced Kwasi Kwarteng as Chancellor amid economic turbulence, is expected to remain at the top of the Treasury.
Hunt has been working towards a highly-anticipated Halloween statement on the government’s medium-term fiscal plans, complete with independent forecast
Opposition parties are all demanding Sunak hold a general election to secure his own mandate to govern.
Truss used her farewell speech to stress the need to be “bold” as she defended the tax-cutting agenda that sparked economic chaos and led to her downfall.
