Stephen Fry triumphed over books by Tony Blair and Lord Sugar to win biography of the year at the Galaxy National Book Awards.

He won the prize for his second volume of memoirs, The Fry Chronicles, at a ceremony attended by stars and figures from the publishing world.

Literary veterans Terry Pratchett and Martin Amis were given awards for outstanding achievement.

Popular fiction book of the year went to David Nicholls' One Day.

Pratchett - the Discworld novelist who has been battling Alzheimer's - said of his win: "I'm amazed. You find something that you like doing and do well and keep on doing it and suddenly they give you an award, when all I was really doing was having a lot of fun."
