The event comes following a historic day for the Prime Minister.
After the sacking of his former Home Secretary Suella Braverman, Mr Sunak made major changes to his cabinet.
Ms Braverman was given her marching orders following a series of controversial comments she made concerning the pro-Palestine protests.
James Cleverly has now replaced Ms Braverman as Home Secretary.
Former Prime Minister David Cameron made his return to politics as Foreign Secretary seven years after stepping down from the cabinet.
Speaking to Sky News, Mr Cameron said: “I know it’s not usual for a Prime Minister to come back in this way but I believe in public service. The Prime Minister asked me to do this job and it’s a time where we have some daunting challenges as a country.”
Therese Coffee also resigned as Environmental Secretary and has been replaced by Steve Barclay who was ousted as Health Secretary.
Vicky Atkins will replace Mr Barclay.
