The three-member jury for one of Canada's richest and most prestigious literary prizes has been announced.

CBC radio host Michael Enright, who fronts The Sunday Edition, joins novelists Claire Messud and Ali Smith on the panel.

Enright, whose journalism career spans nearly 50 years, began his career at The Globe and Mail in 1968. After writing and editing for other publications, including Maclean's magazine, he landed at the CBC in 1974, first hosting This Country in the Morning and then co-hosting As It Happens for a decade.

Enright has been with The Sunday Edition on CBC Radio One since 2000.

American writer Claire Messud's The Emperor's Children was long-listed for the Man Booker Prize for 2006. It was also an international bestseller and was translated into 20 languages.

Messud, who lives in Cambridge, Mass., also writes for Newsweek, the New York Times and the Irish Times.

Born in Inverness, Scotland, Smith is the author of eight works of fiction. Her novel The Accidental captured both the Whitbread Award (2005) and The Orange Broadband Prize for Fiction (2006).

The 2010 Scotiabank Giller Prize long list will be unveiled on Sept. 20, with the shortlist revealed on Oct. 5. The winner of the $50,000 prize will be announced at a gala in Toronto on Nov. 9.

CBC reporter Linden MacIntyre of The Fifth Estate nabbed the 2009 Giller Prize for his book The Bishop's Man.

Created by Toronto businessman Jack Rabinovitch to honour the memory of his wife, literary journalist Doris Giller, the annual prize celebrates the best Canadian novel or book of short fiction published in the past year.
