Emily Maitlis was told off by co-host Krishnan Guru-Murthy after she swore live on air during Channel 4’s US Election coverage.

The ex-BBC journalist was slammed by her fellow presenter on two separate occasions for swearing during the station’s eight-hour broadcast, leading to calls for Ofcom to step in and sanction her behaviour.

Just a few hours in, Ms Maitlis mysteriously vanished from the screen before Mr Guru-Murthy alleged that she ‘started swearing’ and promised to ‘tell her off later’.

But after returning to the studio, she sparked outrage again after letting a swear word slip as she laid into Donald Trump’s claim that illegal immigrants in the US were eating cats and dogs – which she described as ‘bats***’.

Mr Guru-Murthy was forced to step in again by telling the 54-year-old to ‘stop swearing’, before Ms Maitlis then apologised, adding: ‘How else could you describe it?’

At around 5am this morning, Maitlis left the Channel 4 coverage for another work project, which saw Mr Guru-Murthy address his co-host’s on screen behaviour.

He said: ‘I’ll tell Emily off later because I know she started swearing. It may be the middle of the night in Britain but they’re still a little bit sensitive about that stuff.’

Later in the show, the former Newsnight presenter was again told off by her co-host after letting a swear word slip.

She said: ‘It’s not that they disagree about one thing. The whole thing is asymmetric.

‘When Donald Trump talked about eating cats and dogs half of America was thinking, “This is bats***. I can’t believe what he’s saying. This is going to be the end of him”.’

Mr Guru-Murthy then stepped in by saying: ‘Stop swearing. I have to tell [the guests] off for swearing and then you do it’ before Maitlis then apologised.

Elsewhere, during the show former UK Prime Minister Boris Johnson was harangued for promoting his memoir Unleashed, which has been serialised by the Mail.

When asked by 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’.

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.’

Maitlis then 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.’

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.

Results from the presidential election continue to indicate Donald Trump may recapture the White House.

The former president won a wave of states early Tuesday night and looked set to retake several swing states he lost to Joe Biden in 2020, with Trump’s camp saying they were ‘confident’ of victory.

In comparison at Harris’ watch party in Washington D.C. silence descended and supporters were seen hugging as they began to contemplate possible defeat.

Actor Brian Cox also spoke out as his despair at the way the vote was heading while on Channel 4 last night, giving a bleak outlook on a Trump victory.

‘It is the most crucial election there has been in my lifetime and we have to make sure that he [Trump] doesn’t get in, because he is a monster, he really is.

‘He is crazy. He is insane. He wants to be a dictator.

‘It has all been so clear what he has been talking about, I don’t know why the American people aren’t listening to him.

‘The kind of nonsense that he has been talking. I think he has lost it. I think he is deeply mentally unstable.

‘This is not a man who should be the President of the United States.’
