The presenter watched as Dennis swam to the bottom of the tank and through a tunnel in an attempt to collect as many stars for camp as possible.

Decidedly more impressed with the retired footballer’s style of swimming, Ant quipped: “Already a better technique than Iain.”

Then as the 50-year-old retrieved his first star in the Temple Of Gloom task, Ant shouted: “Already a better start that Iain!”

Last month, Iain pulled out of the trial after several attempts to complete it.

The comedian was left in tears after failing to get a single star in the Bushtucker trial. 

At the time he said: "I'm not a strong swimmer. That should have been OK. That box was tiny. I couldn't catch my breath. I just started panicking and erm, yeah, I ballsed up.”

Iain has apparently segregated himself from his fellow campmates amid accusations of bullying. 

In a recent Dingo Dollar challenge, the 44-year-old broke down after quitting the task due to his fear of heights.

But when he returned to camp to break the bad news to the celebrities, they were not forgiving of him pulling out of the trial.

Rebekah Vardy, 35, said: "I think he's a guy that's struggling, but that doesn't excuse bad behaviour and I won't tolerate it."

Meanwhile, Amir Khan added: "I just think Iain should have given it a go."

Viewers of the hit ITV series were furious with the celebrities' lack of support for their fellow campmate and took to Twitter to accuse them of "bullying".
