Ant McPartlin and Declan Donnelly will be left in fits of laughter as I'm A Celebrity... Get Me Out Of Here! star Mo Farah is left screaming in fear in a new trial. 

Mo, 43, will take on new trial Termite Terror in tonight's episode, with the camp voting for him to take part after he and Ashley Roberts both volunteer themselves for the challenge. 

Allowing Ashley, 44, to put her feet up while she celebrates her birthday, instead the former Olympian is sent down to the trial error, where he's tasked with working his way through a series of critter-crawling tunnels. 

Ant, 50, tells him: 'You need to make your way into the termite mound and down into the nest below. Once you're down there, your mission is simple: you must dig, crawl and scramble through the tunnels, collecting stars as you go.'

Navigating the tunnels that have been filled with critters, snakes and a series of nasty surprises, Mo is heard chanting to himself: 'Never give up, never give up!'.

However, it's not long before the former athlete is letting out a series of screams, coming face to face with a series of large snakes crawling around him. 

Shouting and recoiling in fear, co-hosts Ant and Dec, 50, are seen giggling amongst themselves as he struggled, trying not to let Mo overhear their laughter. 

'I remember that from the castle, his little screams,' Ant says, nodding to Mo's former I'm A Celeb appearance in 2020, when the show took place in Wales. 

'Oh, we missed him,' Ant concludes as they watch on as Mo continues to struggle. 

Meanwhile, the remaining celebrities will be marched from camp to take part in a challenge of their own to win treats for camp - this time, competing against each other.

'Celebrities, it’s time for today’s challenge, Balance Of Power. You must all get ready to leave camp now,' Ashley reveals to the rest of the camp. 

At the challenge area out in the South Africa bush, she adds: 'Celebrities, in front of you are two pits and eleven balance paddles. 

'You must each take hold of a paddle and keep it steady to prevent your ball from falling into the pit. When you drop your ball, you are eliminated. The last person standing wins.'

The celebrities are seen battling it out to keep their paddles steady, quickly realising this game is all about endurance, rather than skill - having to stand holding the paddles for as long as possible. 

The group are still standing as night begins to creep in, with a large portion of the celebrities still balancing the balls on the paddles while the eliminated campmates try to distract them in acts of sabotage. 

Deciding to end the game in a unanimous decision, the campmates plan to drop their paddles in order to let one person win - but ITV have teased that not everything could 'go to plan'. 

Back in camp, Harry Redknapp will try and lighten the mood for himself by pulling a prank: pretending there's a new trial in store. 

Pretending to read from a notice board, the former football manager tells his co-stars they must all prepare for a new trial, which he dubs Prison of Hell. 

Stumbling over his words, he manages to fool them by describing the elaborate made-up trial, where celebrities would have to find keys to release themselves from their prison cell. 

But not everyone in the celebrity camp realised Harry is joking right away.  

It comes after Harry revealed the 'truth' behind his awkward mishap with Seann Walsh calling him the wrong name- and the reason he avoided axing David Haye. 

The former football manager, 79, had to choose who left the South Africa camp first after his Lion team fell short to Jimmy Bullard's Rhinos in a tense episode this week.

His options were Gogglebox star Scarlett Moffatt, former Pussycat Doll Ashley, athlete Mo, boxer David and comedian Seann.

Ultimately, Harry opted for Seann, 40, to depart from the camp - and mistakenly called him 'Stewart' in the process.

The former King of the Jungle has now addressed his reasons for the decision - including why the other Lion members were spared, and why he mistook Seann with the wrong name. 

Speaking at an event following the episode's release, Harry said, according to The Mirror: 'So there was a comedian in there called Seann Walsh. Nice guy.'

Harry went on to explain how Seann had told him the show was 'great for his profile' and was hoping to do well in the series by lasting a long time on the ITV format. 

However, Harry was tasked with sending one of his co-stars home, after first attempting to choose himself, only to be told that as 'King', he had to choose from one of his 'subjects'. 

Harry continued, admitting he'd spent a long time thinking over the decision: 'I get into camp and I feel terrible and by the time I get there I have got to tell them who I am sending home. 

'So I'm not gonna send David Haye home, he might knock me out, and I am getting on great with Mo Farah and the girl on the next bed to me was Ashley Roberts. A Pussycat Doll. I'm not sending her home! 

'She teaches me how to do yoga at 7 o'clock in the morning.'

Harry went on to say he had been 'dreading' breaking the news to Seann, due to the pair's prior conversation about Seann wanting to be there.

However, in his worry, the football legend had Seann's name go 'completely blank' out of his mind - accidentally referring to him as 'Stewart' instead.

The other campmates informed him of the mistake, with Harry remarking of sending home the comedian: 'He will hate me'.

'I am dithering and I said "I'm sorry Stewart. I am going to have to send you home", afterwards they all said "Harry, his name is Seann"... he will hate me,' Harry concluded.

Harry appeared to realise the mistake later on, as he could be heard calling Seann by the correct name - and apologised to him.

Meanwhile, David Haye tried to cheer Harry up by saying: 'I always thought it was Shane Walsh.' 

Harry replied: 'I thought it was Stewart didn't I? Did you hear that, my mind went blank. I lost the plot.'

Furthermore, Ant and Dec played into the blunder for laughs during their segments.

The presenting duo joked afterwards that Seann's hotel room was under the name 'Stewart Walsh' - and was booked by Harry. 

I'm A Celebrity... South Africa continues on ITV1 and ITVX.
