Boris Johnson has said he would happily leave his daughter alone with Donald Trump, as he backs the ex-President in a Channel 4 election special.

The former UK PM and Mail columnist clashed with fellow panellist and ex-adult film star Stormy Daniels when she pushed him on whether he would feel comfortable leaving his children alone with the Republican candidate.

‘My experience of Donald Trump is that when I’ve known him… I hear what you say and maybe I’m wrong but he has been courteous, he has been polite,’ Johnson said, before being cut off by Emily Maitlis.

‘He denied an election that he lost. What does it matter if he’s courteous if he can’t accept the results of democracy and the American voter?’ she retorted.

‘And you’ve heard several people, including me, say that they think that was a terrible thing to do,’ Mr Johnson replied.

He later came back to the point, reifying that there was ‘the orderly transition of power from one administration to the next under the Constitution’.

‘Whatever you say about Donald Trump now he has been contesting this election democratically, fighting for every vote he can get… and as we speak tonight we don’t know what the outcome is going to be,’ he said.

Daniels, 45, also spoke candidly of her anxieties about how Trump’s supporters behaved since she became publicly linked with the former president in the coverage overnight.

‘[Trump supporters] aren’t hiding anymore. They’re using their real screen names, they’re using their real phone numbers.’

‘The threats are more graphic, more targeted, and as we all know when I testified back in May, Trump’s attorneys “accidentally” put a document on the screen of the courtroom that had nothing to do with the case that we were trying that day with my unredacted home address.

‘So I haven’t been home since July, I have been living in an RV and travelling,’ she revealed.

Ms Daniels also claimed that Trump supporters had been calling in threats to live comedy shows she was hosting.

‘Trump supporters were calling in droves and threatening club owners [with] burning down the clubs.’

Mr Johnson was also harangued by the stations presenter Krishnan Guru-Murthy for promoting his memoir, which has been serialised by the Mail, before he joked after Mr Johnson had left that he had been ‘fired for banging on about his book’

When asked by fellow presenter Emily Maitlis if he still wanted Trump to win, the Mail Columnist joked: ‘Well, as I say in my book Unleashed..’, to which Mr Guru-Murthy interjected saying ‘put it away, stop it, enough’.

The Mail columnist was later replaced on the panel by Michael Cohen, a former lawyer to Trump. However, there is nothing to suggest that this switch wasn’t part of the planned evenings programme.

Also while live on air, Johnson was mid-way through a point about incumbent president Joe Biden being forgetful and repeating things in meetings when he was abruptly cut off, so the station could head into a break.

During the panel discussion, Mr Johnson said he met with former US president and Republican nominee Donald Trump after his attempted assassination in July.

‘In case I failed to mention this, I am promoting my book Unleashed, and I had a talk with him about Ukraine,’ he joked to the camera, as he held up a copy of his book.

When asked about following in Mr Trump’s footsteps regarding a political comeback if he was to win the presidential election, Mr Johnson said: ‘The answer is obviously contained in Unleashed where you’ll find the full discussion of this subject.’

Co-host Emily Maitlis told him: ‘We are not all going to read your book, so just tell us, do you want to have a political comeback… You can’t actually answer a single question.’

Mr Johnson responded: ‘By the way Emily I’ve answered all your questions all night.

‘Currently I am blissfully engaged promoting my book Unleashed, available in all good book stores.’

Guru-Murthy later jokingly told viewers: ‘Boris Johnson has been fired for banging on about his book.’

Mr Johnson, 60, has been promoting his new memoir titled Unleashed after it was released last month.

The 784-page book looks back on Mr Johnson’s time as prime minister – from 2019 to 2022 – including Brexit and the Covid pandemic.

Channel 4 newsreader Guru-Murthy is at the helm of the channel’s first overnight US election programme since 1992 alongside former Newsnight presenter Maitlis.

Political pundits, and a number of famous faces including Mr Johnson, joined the hosts in the Washington DC studio as the American public decides whether Democratic nominee Kamala Harris or Mr Trump becomes president.

Guests on the programme include Republican supporter and reality TV star Caitlyn Jenner, and Stormy Daniels, the woman at the centre of Mr Trump’s hush money trial following an affair between the two.

At one point, Ms Daniels pointedly asked: ‘If you were prime minister and you and Donald Trump got into a disagreement, as people do with Donald Trump, would you have any fear for the ladies in his life?’

Mr Johnson said: ‘Nothing like that came up. When you’re talking to the US president, the relationship you have as UK prime minister is one of great formality and importance.

‘Of course you develop a friendship, but actually, and I can say this in all sincerity, I never in my time with him was treated with anything other than courtesy and friendliness.’

Speaking to Ms Daniels, he said: ‘Now you had a very different experience, but I can only talk about mine.’
