Frankie Boyle has promised to donate the £54,650 he won in libel damages to prisoners' rights group Reprieve.

The comedian won the damages after a High Court battle with the Daily Mirror, which had described him as 'racist' and claimed he had been forced to quit Mock The Week.

Boyle wrote on Twitter: 'Here's the good people I'm giving my damages to. They do a lot of inspiring work.'.

Clive Stafford Smith, the director of Reprieve, said it was 'very generous', adding: 'The funds will be put to good use for those people who need it..

Reprieve was set up to enforce the human rights of prisoners, from death row to Guantanamo Bay. It says: 'We promote the rule of law around the world, and secure each person’s right to a fair trial.'
