Fingerprint and firearms experts have rejected claims Robin Bain had gunpowder marks on his fingers, police say.

Police doubt marks seen on fingerprints of Robin Bain are the result of him having loaded a gun before his death, but David Bain supporter Joe Karam has rubbished their conclusion.

New evidence has emerged which completely clears David Bain and he deserves an immediate pardon, his lawyer, Michael Reed QC, says.
