Billy Connolly has revealed that he thinks Robin Williams called him to say "goodbye" before taking his own life.

The Scottish comedian told the Daily Telegraph that he often shared his experience of Parkinson's disease with fellow sufferer Williams, and that they had a close friendship.

Describing him as "my pal", he said: "He was not always depressed. He was a complicated man, but a beautiful person. He was a joy.

"We used to talk about Parkinson's a lot, he would call me and we would compare notes.

"His was early on-set, the same as mine. Everybody worries about it. It's like a mugger following you around."

And he revealed that in their last phone call, made by Williams, the actor had been keen to express his feelings.

"We told each other we loved each other, I told him and he told me many times. I never stopped it and he never stopped telling me.

"As a matter of fact, I thought afterwards he tried to say goodbye to me, because he got very luvvie towards the end. It's fanciful but that's what I told myself.

"On the last phone call he said, 'I love you like a brother' and I said, 'I know you do' and he said, 'Are you sure you know?' and I said, 'Yes'. Robin worried about everything."
