As if by magic, Mr Benn reappears

You might not recognise the name David McKee, but you are probably familiar with one of his creations.

He is the man who created Mr Benn.

The character inspired a cartoon, which was recently voted one of the most-loved children's television programmes of all time.

A new art exhibition featuring David McKee's work has just opened in London.

BBC Breakfast's Tim Muffett went to meet him.
