Scottish comedian Ronnie Corbett has told how he has a habit of getting locked in the loo when he is at major events.

The 83-year-old star said it had happened at more than one royal occasion.

During his most recent scare he had to be passed a screwdriver to free himself in time to give a reading at a memorial service.

The former Two Ronnies star also brushed off a report he was retiring due to illness.
