LONDON (AFP) - The winner of Britains Man Booker prize for literature is announced on Tuesday, but the ceremony has been overshadowed by the launch of a rival award that claims the Booker has become too populist. Julian Barnes remains the favourite for his novel The Sense of an Ending, while debut novelists Stephen Kelman and A. D. Miller are also among the six finalists, made up of four Britons and two Canadians. One of the highest-profile awards in English-language literature, the 50,000 ($80,000, 57,000 euros) annual Booker is awarded for the best work of fiction by an author from the Commonwealth or the Republic of Ireland. But this years shortlist has disappointed the Londons literati, while there has also been criticism of the fact that the prize judges include a former head of Britains domestic intelligence agency MI5. Last week an anonymous group calling itself The Advisory Board of the Literature Prize said it planned to knock the Man Booker off its perch as the benchmark of literary taste. The Literature Prize would also include novels by American writers in the hunt for the best novel written in the English language and published in the UK in a given year. In a statement issued last Wednesday, the board for the new prize said it would honour novels that were unsurpassed in their quality and ambition, saying that for many years this brief was fulfilled by the Booker. Shortlist for the 2011 Booker Prize: - The Sense of an Ending by Julian Barnes (Britain) - Jamrachs Menagerie by Carol Birch (Britain) - The Sisters Brothers by Patrick deWitt (Canada) - Half Blood Blues by Esi Edugyan (Canada) - Pigeon English by Stephen Kelman (Britain) - Snowdrops by A. D. Miller (Britain)
