Jeremy Corbyn has said he cannot name one mistake he has made as Labour leader because there have been too many.

Mr Corbyn also admitted he has kept hundreds of personal diaries - and suggested that they may one day be published.

On Good Morning Britain, Piers Morgan compared Mr Corbyn to the Arsenal manager Arsene Wenger, accusing them both of clinging onto and ruining important institutions.

He also said the two would not admit to making mistakes.
