The 82-year-old portrayed the Sixth Doctor, preceded by Peter Davidson and succeeded by Sylvester McCoy, staying in the role from 1984 until 1986.
He has since reappeared in the show alongside the Thirteenth Doctor, Jodie Whittaker, and also took part in the 12th series of I’m a Celebrity… Get Me Out of Here!, finishing in eighth place.
Appearing at Abbey-Con 2025 in Abingdon, Oxfordshire, Mr Baker had an exclusive chat with the Oxford Mail.

His iconic role of the Doctor was most recently played by Scottish star Ncuti Gatwa before the Barbie regenerated back in May.
Departing the titular role, he changed into Billie Piper, which surprised fans as the Swindon actress had previously played fan favourite companion Rose Tyler alongside Christopher Eccleston and David Tennant.
When asked for his thoughts on the shock regeneration, Mr Baker said: “I don’t have a clue, but I suspect it’s a load of old malarky.

“I think they didn’t know what to say, so they did that. I think there will be something involving Billie Piper, but she’s not the Doctor, who can she be?
“She’s someone else! It’s like me being the Master, well, I could be, I suppose.
“I suppose she could be a lookalike, but they could come up with anything, and that is the joy of the series.
“You can do anything with it, so if they choose to do it, they could.”

When prompted to name who he’d like to see next in the iconic role of the Doctor, Mr Baker said: “I think it would be quite nice if it was someone completely different.
“I’d pick my daughter Rosie, she’d be very good.”
The former timelord lives close to the Oxfordshire border and is set to star in a play in Henley next week.
Speaking at Abbey-Con 2025, he said: “It’s lovely, yes. I live not far from here, between Marlow and Henley, so I’m in the area.”

“Last year I was touring as Sherlock Holmes in The Hound of the Baskervilles, and this year we are doing The Sign of the Four.
“Terry Malloy, who played Davros in Doctor Who, is Doctor Watson, and I’m Sherlock Holmes.
“It’s like a radio play on stage. Last night we were in Bishop’s Stortford, before that was Newark- we are getting all over the place.
“We shall be at Henley at the dear old Kenton (theatre) next week. I’m less than ten miles away from the town, so that’s alright; it’s my local shopping area!”
