I'M A Celebrity co-hosts Ant McPartlin and Declan Donnelly continued their tradition of mocking the Prime Minister during the show’s grand finale.

The presenting duo joked that Boris Johnson had signed up to appear on the ITV series in 2022.

The pair have made jokey references to Johnson in several episodes, addressing him directly on some occasions.

Introducing the next segment during Sunday’s final, McPartlin said: “Shortly we will be crowning your winner but before we do, let’s go back to our three finalists and their last meal on I’m A Celebrity 2021.”

Donnelly added: “Before we do that and before we bring the curtain down on this year’s show, we are always looking ahead. Rest assured folks, we are looking ahead.”

Holding up a campmate T-shirt with the name Boris on it, he added: “We can let you into a little secret. We have already booked our first celebrity for next series, next year, already.

“So that is something to look forward to. Evening Prime Minister.”

The pair were even mentioned in Parliament after they referenced an alleged Christmas party held at Downing Street during the 2020 lockdown.

While introducing the next part of Tuesday’s episode, Donnelly said: “It is all changing in camp now because yesterday the celebs chose a new leader via the gift of a secret vote.”

McPartlin continued: “That means David’s reign is over. But they weren’t celebrating. They categorically deny any suggestions that they had a party. And this fictional party definitely didn’t involve cheese and wine, or a secret Santa.”

Once again, Donnelly looked directly into the camera and added: “Evening Prime Minister… for now.”

Their antics were noted at Prime Minister’s Questions on Wednesday, with Labour leader Sir Keir Starmer denouncing an investigation into the incident which has been ordered by Johnson.

In an earlier episode of I’m A Celebrity, following the election of a new camp leader, Donnelly asked: “Exciting stuff, but what exactly, though, does the leader do?”

McPartlin replied: “Well, they look increasingly dishevelled, give cushy jobs to their mates, and pretty much make it up as they go along.”

Donnelly then looked towards the camera with a grin and quipped: “Evening, Prime Minister.”

Later while checking a written note, Donnelly performed an impression of Johnson’s speech at the Confederation of British Industry conference last month, muttering “forgive me” several times.

During the speech, the Prime Minister lost his place for 20 seconds and then went on a tangent about a visit he had made to Peppa Pig World in Hampshire.

The I’m A Celebrity final had a 10 minute delayed start due to the Prime Minister holding a Downing Street press conference earlier on Sunday evening.

The Prime Minister delivered a pre-recorded address to the UK at 8pm to provide an update on the vaccine booster programme in light of the new Omicron variant.
