Several key Conservative Party have come out in public support of their preferred new Prime Minister.

There will likely be three names on the ballot as the race to No 10 restarts on Monday.

The resignation of Liz Truss, and the search for her replacement, has led to a flurry of lobbying between Tory camps.

Boris Johnson is back in the UK, Rishi Sunak is said to already have 100 backers and Penny Mordaunt – the only confirmed candidate so far – has released a new campaign video ahead of next week.

Candidates will have until 2pm on Monday to secure 100 nominations.

As the days dwindle until the crunch deadline, and lobbying gathers pace, who is backing who?

Priti Patel

The former Home Secretary, who resigned last month, has pledged her support to her former boss.

Ms Patel and Mr Johnson worked alongside each other on some key, and controversial, policies.

The introduction of their plan to deport people who arrive in Britain outside of the legal channels to Rwanda faced major backlash.

Ms Patel tweeted today: ‘Boris has the mandate to deliver our elected manifesto and a proven track record getting the big decisions right. I’m backing him in the leadership contest.’

Dominic Raab

Dominic Raab has thrown his support behind Rishi Sunak, stating he has the ‘plan and credibility’ the country needs.

He has also been vocal in his opinion on whether Mr Johnson should be handed back the keys to No 10.

The former PM still faces an investigation by the Commons Privileges Committee over claims he lied to Parliament over lockdown parties in Downing Street.

Mr Raab told the BBC: ‘The challenge is this Committee on Privileges and Standards is entering a new phase, there’s going to be oral testimony from people from Number 10.

‘We cannot go backwards. We cannot have another episode of the Groundhog Day, of the soap opera of partygate. We must get the country and the government moving forward.’

Jacob Rees-Mogg

Mr Rees-Mogg has said Tory party members should decide who is the next leader rather than MPs, telling the Daily Telegraph’s Chopper’s Politics podcast that returning Mr Johnson to No 10 would calm the stock markets.

The Business Secretary added that doing so would mean the general election would not need to be held until late 2024.

Mr Rees-Mogg said: ‘I’m always in favour of the members deciding the leadership – I think that’s the right place for it to go. And I think the 1922 Committee and the Board of the Tory Party have done really well to get it to a position where that can be done swiftly. I’m in favour of it going to the membership.’

He went on to say that it was ‘an error’ for Tory MPs to dump Mr Johnson, adding: ‘Boris Johnson’s attraction is that he is a big, charismatic political figure who is able to get things done and who is able to connect with voters in a way that no other politician of this era can.’

Andrea Leadsom

Dame Andrea Leadsom has backed Penny Mordaunt with her fresh attempt to become Prime Minister.

The former cabinet minister took to Twitter to voice her support for the only candidate who, so far, has announced their bid to run.

Dame Leadsom cited Ms Mordaunt’s ‘compassion’ and ‘determination’ in her short tweet.

She wrote: ‘Penny has the experience, the compassion and the determination to lead our country to a bright future’, before adding the hashtag #PM4PM.

Sajid Javid

Former British finance minister Sajid Javid has endorsed Rishi Sunak to be the next Prime Minister.

He argued it was ‘abundantly clear’ the former chancellor ‘should be the next Prime Minister’.

The pair resigned with minutes of each other earlier this year, a move that paved the way for the demise of the Johnson leadership era.

On Twitter, Mr Javid wrote: ‘It is abundantly clear that Rishi Sunak has what it takes to match the challenges we face – he is the right person to lead our party and take the country forward.

Nadine Dorries

A staunch ally of Mr Johnson, it’s no surprise who Ms Dorries has pledged support to.

The MP Mid Bedfordshire tweeted: ‘The boss is back. The man who broke the Brexit deadlock, delivered the first Covid vaccine, supported Ukraine when no one else would.

‘The one person Labour fear the most is Boris Johnson #BringBackBoris.’

Ben Wallace

Boris Johnson appears to have also won the backing of Ben Wallace.

The defence secretary, who ruled himself out of the contest earlier this week, was questioned on his preferred candidate on Friday.

Mr Wallace revealed he would ‘lean towards’ supporting Mr Johnson.

He added: ‘I think he will still have some questions to answer about that [Partygate] investigation.

‘He got a mandate and I think that’s an important thing for all of us to bear in mind.’
