Tory MP Ann Widdecombe has resigned as patron of an anti-bullying charity after it claimed No 10 staff had used its helpline.

She said publicising the phone calls had been a breach of confidentiality.

Lord Mandelson was responding to extracts from a new book in the Observer newspaper by its chief political commentator Andrew Rawnsley.

Downing Street has already rejected the paper's claims that the prime minister mistreated staff and was investigated over the issue by a top civil servant.
