Ant McPartlin has announced that he will be taking more time away from work, with co-host Declan Donnelly set to present I'm A Celebrity… Get Me Out Of Here! without him later this year, and Ant and Dec's Saturday Night Takeaway taking a "rest" in 2019.
McPartlin has been receiving treatment for alcohol addiction following a drink-driving charge earlier this year which saw him banned from driving for 20 months and fined £86,000.
The 42-year-old has announced he will be taking the rest of the year off in a bid to focus on his recovery, which he says is "going very well."
"My recovery is going very well and for that to continue having spoken to Dec and ITV, I have made the decision to take the rest of the year off," McPartlin said in a statement.
"I'd like to thank both Dec and ITV for their continued support and I look forward to getting back to work in the new year."
McPartlin's close friend and colleague Declan Donnelly said he is "obviously sad" at the prospect of filming I'm A Celeb without him, but is "fully supportive" of his choice.
"Whilst I am obviously sad at the thought of being without my best friend in Australia this year, I am proud of the work Ant has been doing privately and I am fully supportive of his decision," Donnelly said.
"I'm looking forward to us both being reunited on screen in 2019."
A statement on the stars' website said they had "made the joint decision not to present a new series of Ant & Dec's Saturday Night Takeaway in Spring 2019".
"Production and filming for a Saturday Night Takeaway series in February would normally have already started, and continue throughout 2018 and early 2019," the statement explained.
"Neither Ant & Dec nor ITV wanted to compromise the quality of the show and therefore felt it was better to rest the series next year. They will instead bring the show back in 2020, bigger and better than ever."
Donnelly presented episodes of Ant and Dec's Saturday Night Takeaway on his own this year and also took the helm of presenting the live Britain's Got Talent shows, with McPartlin only featuring on the pre-recorded audition segments.
