Rishi Sunak will make his first Commons appearance as Prime Minister on Wednesday as he works to unite his party and restore the UK’s economic credibility.
He is set to square off against Sir Keir Starmer later fresh from appointing a new Cabinet that he hopes will bring some political stability to the country.
This comes after Mr Sunak culled nearly 12 of Ms Truss’ top-tier ministers such as Jacob Rees-Mogg while reviving the careers of the likes of Suella Braverman, Dominic Raab and Michael Gove.
On Wednesday, Prime Minister’s Questions will give an insight into how unified the party is behind its new leader after Sunak used his first public address on Tuesday to brace the country for “difficult decisions” as he criticised much of the legacy left behind by Liz Truss’ brief period as PM.
Rishi Sunak meets King Charles to be appointed Prime Minister
“Some mistakes were made. Not born of ill will or bad intentions – quite the opposite in fact. But mistakes nonetheless,” he said.
“I’ve been elected as leader of my party and your Prime Minister in part to fix them – and that work begins immediately.”
Volodymyr Zelensky and Joe Biden were among the first world leaders Mr Sunak spoke to on Tuesday evening, as he told the Ukrainian president that the UK’s support for the war-torn country would be as “strong as ever under his premiership”.
Scottish First Minister Nicola Sturgeon and Welsh First Minister Mark Drakeford were two others he spoke to.
It’s expected that Sunak’s new-look Cabinet could first meet as early as this morning which would see the new PM’s allies gather, former Truss backers and figures too from the right wing of the party.
A No 10 source said that the new Cabinet “brings the talents of the party together” and that it reflects a “unified party”.
Mr Raab, one of Sunak’s loyalists given key roles, was appointed Deputy Prime Minister and won a return to Justice Secretary.
Mark Harper is now Transport Secretary, while former Education Secretary Sir Gavin Williamson returned to Government as minister without portfolio in the Cabinet Office.
Both opponents and rivals took some spots too with Penny Mordaunt kept in place as Commons leader while Truss ally Therese Coffey became Environment Secretary.
Michael Gove has returned to his old role of Levelling Up Secretary while Defence Secretary Ben Wallace and Foreign Secretary James Cleverly are to stay in their jobs.
The return of Suella Braverman to Home Secretary is the most controversial, just days after she dramatically quit the Government after being accused of breaching the ministerial code.
Mr Sunak, who earlier promised that his new Government would be one of “integrity”, immediately faced questions about the decision to re-hire Ms Braverman as Labour accused the new PM of “putting party before country”.
In the coming days, it’s likely details of what policies Mr Sunak and continuing Chancellor Jeremy Hunt might pursue could come to light as the pair ponder how to fill the multi-billion pound fiscal black hole inherited from the Truss administration.
While the fiscal statement is still scheduled for October 31, there is speculation of it shifting to a new date.
Tory MP Richard Holden told BBC Newsnight on Tuesday that details would likely emerge over the next week.
“I think there’s a huge amount of different things to look at. We’ve got to look at those as a package,” he said.
