Pamela Stephenson said her husband was rushed to hospital in a taxi after developing the potential deadly clot - but revealed he still found time to crack jokes about her driving on the way.

Ms Stephenson, 64, said the comedian was "in agony and crying with pain" as they travelled to the hospital.

The actor added: "The road was in a very bad condition, so the taxi was bumping over it, and Billy was saying, 'Uh-oh, he drives just like you, Pamsy!'

The Glaswegian comedian was diagnosed with prostate cancer and Parkinson's disease on the same day. He underwent a surgery in 2013 and has been since given the all-clear from prostate cancer.
