The former Prime Minister of the United Kingdom, David Cameron is set to return to the cabinet table for the first time in more than seven years on Tuesday after his recall to government.
Current Premier Rishi Sunak will meet his new cabinet after a dramatic overhaul on Monday saw the former prime minister return to frontline politics.
He replaces James Cleverly, who was moved to be home secretary to take over from Suella Braverman.
Braverman was dropped following her criticism of the Metropolitan Police.
Lord Cameron, as he is now known as of his appointment to the House of Lords on Monday, had been out of Parliament since he stood down as prime minister in 2016.
His return to politics came out of the blue, with Downing Street managing to prevent any rumours of the appointment from leaking, despite the fact the job offer was made last week.
In one fell swoop, No 10 revealed not only was the former prime minister entering the House of Lords, he would also be taking up one of the most senior jobs in government.
While the news was still being digested in Westminster, Lord Cameron was carrying out official duties, including holding a call with US Secretary of State Antony Blinken.
The pair "reiterated the strength and depth of the relationship between the UK and the US", the Foreign Office said, and spoke about the war in Ukraine.
In a statement, the Foreign Office said: "They discussed the conflict in the Middle East, Israel's right to self defence and the need for humanitarian pauses to allow the safe passage of aid into Gaza."
In a speech at the Lord Mayor's Banquet in London on Monday night, Mr Sunak said he was "pleased to have appointed a new foreign secretary" and said the new cabinet is "a united team".
Richard Holden, the newly-appointed Conservative Party chair, told BBC Breakfast that Lord Cameron had returned "out of a sense of duty" and would bring experience to the role.
