Sir David Jason has revealed he had "seriously bad" Covid this summer, which resulted in the actor collapsing when getting out of bed one night.

"I got it seriously bad," he said. "Because all the muscles weren't working, I collapsed and I fell against the radiator... I was so weak, I couldn't get up."

Explaining that he had got up to go to the toilet, Sir David told Breakfast's Jon Kay: "I crawled to the bed. The muscles weren't working and I used the bed to try and stand up...

so that I could go to where I wanted to get, and also get back into bed, and I couldn't… "I tried for about a quarter of an hour, trying all sorts of things to stand up so I could walk about."

He tried to get to the door, but said: "My arms wouldn't work and my legs wouldn't work, so being a very creative and inventive person, I thought, how will I get from here to the door?

Sir David has now recovered and is publishing a book about Christmas, including stories from the making of the Only Fools and Horses festive specials.
