Sir Trevor McDonald will present his final News at Ten broadcast on ITV1 next month, he has confirmed.
The veteran broadcaster will step away from the presenter's chair after coverage of the US presidential elections concludes.
Mark Austin, a current part of the News at Ten team, will become Julie Etchingham's co-presenter following Sir Trevor's departure.
"I've made no secret of the fact that I cannot be in the presenter's chair forever," the 69-year-old said.
He will still be seen on his Tonight programme and will host high profile documentaries.
"I've tremendously enjoyed the opportunity to help re-establish News at Ten over the last year and to work alongside Julie Etchingham, who is a fantastically talented journalist," Sir Trevor added.
"Anchoring ITV News's live coverage of a hugely exciting and historic US election seems the opportune moment to leave on a high."
The popular newsreader has presenter News at Ten since the nightly bulletin returned to UK screens in January this year, having been axed in 1999.
"Sir Trevor McDonald is the leading news broadcaster of his generation and is responsible for many landmark television news moments," said ITV's Peter Fincham.
"While I'd like to pay tribute to his work for ITV News and ITN over the last 35 years, I am delighted that he will be staying with the network and working on a range of projects for ITV1."
The actor says he isn't "holding out for more money or doing anything like that".
The drama will be making its return to the streaming service in the near future.
