Sir Billy Connolly has described himself as the “least patriotic man in the world” and said he dislikes people who “write England off because they’re Scottish”.

The Scottish actor and comedian, also known by his moniker The Big Yin, will be seen in the first episode of Sky Arts series Tate Britain’s Great Art Walks, where he joins Gus Casely-Hayford on a walking tour which will focus on the influences of English painter Stanley Spencer.

Asked about his choice of doing the programme which focuses on a British painter, as a Scotsman, he told Radio Times: “I’m the least patriotic man in the world. I do love Scotland, but if the love for your country is all you have, you’re in a desperate state.

“I dislike people that write England off because they’re Scottish. It’s unfair and brutal.”

The Glasgow-born star, 75, who has enjoyed a successful acting career alongside his life in comedy, revealed in 2013 that he was being treated for the initial symptoms of Parkinson’s disease.

He was knighted at Buckingham Palace in 2017 and said being given the honour was “a big bit nerve-racking”.

He told Radio Times: “You don’t want to make an arse of it. You think, “Oh God, don’t trip.” Or worry you might make a rude noise.

“Since I’ve got Parkinson’s, I’m a bit dodgy getting down on one knee – I don’t do it all that well. And then I had to walk backwards to a certain point, but I managed it fine.

“I’m sure Prince William will think I’m a mentally ill person. I answered his questions in the most stupid fashion just though nerves.”

He added: “If you listen to the song The Glory of Love: “You’ve got to give a little, take a little/Sometimes let your poor heart break a little/That’s the story of, and that’s the glory of love.” It’s all in there.”

He revealed the couple watch the Oscars ceremony annually and he makes “macaroni and cheese. It’s a ritual”.
