A salesman from Suffolk, who's serving life in prison for murdering his ex-girlfriend, has lost a fight at the UK's highest court to have evidence in the case looked at again.

Supreme Court justices unanimously rejected an appeal by Kevin Nunn. He was convicted in 2006 of the murder of Dawn Walker after her partially clothed body was found on the bank of the River Lark in Suffolk.

He claims he's innocent and his family have always insisted he is too.

Nunn's legal team were trying to get Suffolk Police to give them access to key forensic evidence linked to the case that they say wasn't properly examined at the time.

This includes sperm found on Miss Walker's body after she died in February 2005. The original investigators were unable to get a full DNA profile from it.

Nunn was refused permission to appeal against his conviction in 2007, and in 2012 his attempts to get Suffolk Police to give access to key exhibits were also turned down.

Prosecutors said he killed Miss Walker in a jealous rage after she left him for a man who she had previously had a relationship with.
