Last month three judges dismissed the appeal of Barry George, the man convicted of killing the TV presenter Jill Dando, saying they had "no doubt as to the correctness of the conviction".

Michelle Diskin, Barry George's sister joins Jenni Murray to talk about about her fight to clear her brother's name.
