Forty years after it was first published, Troubles, by late JG Farrell has been announced as the winner of the Lost Man Booker Prize - a one-off prize to honour the books published in 1970, but not considered for the prize when its rules were changed.

It won by a clear majority, winning 38 per cent of the votes by the international reading public, more than double the votes cast for any other book on the shortlist. J G Farrell died in 1979.
