Sunak set to enter No. 10 Downing St as PM

Preparations were underway in 10 Downing Street on Tuesday morning, ahead of the arrival of incoming British Prime Minister Rishi Sunak.

Sunak will be asked by King Charles III to form a government and will become the prime minister in a handover of power from Liz Truss on Tuesday.

Truss quit last week after 45 tumultuous days in office. Sunak will be the country's third prime minister since September.
