But which actors sit alongside him for playing the same role for the longest time?
William Roache - Coronation Street, 63 years
William Roache, 91, holds the Guiness World Record for longest serving actor in a television soap.
He has starred in Coronation Street as Ken Barlow in the ITV soap opera since 1960.
His character had to be temporarily written out of Corrie in 2020 due to the coronavirus pandemic, but he returned after a few months off screen to socially distanced filming in order to protect him from catching the virus.
But as Roache celebrated his 90th birthday with a special ITV documentary Happy Birthday Bill he insisted he has no plans to retire.

Roache said: "People will say when are you retiring? Are you going to take a break? But then what happens?
"Whilst I can do it, and whilst they will have me, I have no intention of retiring. I am so fortunate to work for an organisation that is happy to have me."
Sir David Jason, Open All Hours, 43 years
Sir David Jason, 83, is perhaps best known as Del Boy in Only Fools And Horses, but that show has only managed 22 years.
He began starring as shop boy Granville alongside Ronnie Barker in sitcom Open All Hours in 1973. The popular show ran for four series until 1985.
Then in 2013, eight years after Barker's death, the show was revived as Still Open All Hours, with Granville now running the corner shop himself.

She died in March 2022 aged 82, having done a stint in EastEnders as Jane Beale's mum Linda Clarke.

Chris Chittell - Emmerdale, 37 years
Chris Chittell, 75, may not have been in Emmerdale Farm when it first started in 1972, but he is currently the rural soap's longest-serving actor.
Eric Pollard arrived in Emmerdale 37 years ago in 1986 as a crooked businessman and quickly made a lot of enemies.
During his time in the soap he has been the centre of many storylines, including struggling with grief after the death of his beloved wife Val in 2017. And in 2022 he helped the show celebrate its 50th anniversary.
Pollard has said of leaving the show: "I can see Pollard heading downhill in five or 10 years' time. But you're only ever as good as your last storyline.
"I've always said that when the writers stop writing for Pollard, I'd leave. And although I'd hate it, I'd just shake everyone's hand and say thank you very much, as the journey has been wonderful."
Nancy Cartwright - The Simpsons, 36 years
Nancy Cartwright, 65, first voiced wayward schoolboy Bart Simpson in a short animation on The Tracy Ullman Show in 1987.
She has now played the role in animated comedy The Simpsons for 36 years to date, tying with co-stars Dan Castellaneta and Julie Kavner who voice Bart's parents Homer and Marge.

June Brown - EastEnders, 35 years
June Brown starred in EastEnders for 35 years before she quit the show in 2020.
The soap actor — who died at the age of 95 in 2022 — will always be remembered as chain-smoking laundrette manager Dot, one of the original residents of Albert Square when the BBC soap launched in 1985.
Dot left Albert Square to live in Ireland when Brown announced her retirement.

The former child star — who had appeared in EastEnders and Grange Hill — has become an integral character to the soap as Tony Hutchison.
During his 28 years in the show he has survived a brain tumour and been married three times, including to Mandy Richardson and Cindy Cunningham.
Nick's brother John Pickard also joined the soap as Dom Reilly in 2005, bit only lasted five years.
Stefan Dennis - Neighbours, 18 years
Stefan Dennis, 64, appeared as Paul Robinson when Neighbours first began in 1985.
Harold Bishop actor Ian Smith may be older, but he didn't join until 1987.
Dennis took a break from the show in 1993 and did not return until 2004.
But even at 18 years he is the longest serving character on Ramsay Street.
And Aussie series Neighbours has just been saved by Amazon after getting the axe so Dennis still has time to clock up more soap service.
