Among the top appointments are new Chancellor Kwasi Kwarteng, new Home Secretary Suella Braverman, and Foreign Secretary James Cleverly.
Ms Truss set about quickly shaping her top team, sacking prominent Rishi Sunak backers Dominic Raab, Grant Shapps, and Steve Barclay, shortly after giving a speech to the nation from outside No10.

Liz Truss loyalist, Kwasi Kwarteng, has been confirmed as the next Chancellor of the Exchequer, as widely expected.
Mr Kwarteng, who has served as Business Secretary since 2021, will face the daunting task of helping to craft the Government’s response to the energy price crisis.
A vocal supporter of Liz Truss, James Cleverly has become the next Foreign Secretary.
Mr Cleverly was previously the Education Secretary and has also previously served as a minister in the Foreign Office.
Suella Braverman, the Attorney General, has taken over from Priti Patel as Home Secretary under Liz Truss.
Ms Braverman launched her own bid to become Prime Minister but was knocked out in a vote of MPs and so did not appear on a ballot before Conservative Party members.
Health Secretary and Deputy Prime Minister
Considered to be among Ms Truss’s closest friends in politics, Therese Coffey became the new Health and Social Care Secretary, taking over from Steve Barclay. She was also made the new Deputy Prime Minister.
The former Department for Work and Pensions Secretary will face the challenge of sorting a plan for the NHS without the guarantee of extra funds from the soon-to-be-canned national insurance hike.
Ben Wallace will continue in his role at the Ministry of Defence. The popular Cabinet minister was a favourite for the top job of Prime Minister in early polling of Tory members, but later ruled himself out of the contest.
The former Northern Ireland Secretary, Brandon Lewis, who initially backed Nadhim Zahawi before pledging his support to Ms Truss, has taken over Dominic Raab as Justice Secretary.
Levelling Up Secretary
The Chief Secretary to the Treasury, Simon Clarke, has taken over as Levelling Up Secretary, previously held by Greg Clark, and by Michael Gove.
International Trade Secretary
Kemi Badenoch, was confirmed as the new International Trade Secretary, taking over from Anne-Marie Trevelyan.
Ms Badenoch, who performed well in the Westminster stage of the leadership contest finishing fourth, had been tipped for a role in Ms Truss’s team.
Kit Malthouse, the former Chancellor of the Duchy of Lancaster will be the new Education Secretary.
This is more of an unexpected appointment than some of the others, as some had tipped Michelle Donelan, who resigned from the post less than 36 hours after accepting it as Boris Johnson’s premiership collapsed around him in July, to take the post instead.
Work and Pensions Secretary
Ms Truss’s fellow Norfolk MP Chloe Smith will take over Therese Coffey’s former role at the Department for Work and Pensions.
Anne-Marie Trevelyan was appointed as Transport Secretary, taking over the portfolio from Grant Shapps.
Ms Trevelyan had previously been International Trade Secretary. She will face dealing with a slew of strikes affecting the transport network.
Jacob Rees-Mogg, the minister for Brexit opportunities and Government efficiency has been confirmed as Business Secretary.
He said a new package would be brought forward to help households with energy bills, but declined to go into details, in an interview with Sky News after his appointment.
Ranil Jayawardena was appointed as the new Secretary of State for Environment, Food and Rural Affairs.
