Rishi Sunak is set to become the UK’s latest Prime Minister this week, replacing the country’s shortest-serving leader of all-time, Liz Truss.

He will become the third person to lead the country in seven weeks, and the fifth since 2016.

It means yet more turnover at the heart of government – Boris Johnson and Truss both frantically reshuffled their Cabinets as they fought to save their jobs, and Sunak will be expected to bring in his own team this week.

But Sunak will face immediate calls for a general election from opposition parties, who will demand he seeks his own mandate in order to govern with any authority.
