Northern Ireland's Court of Appeal has dismissed the appeal of two Co Armagh men who were convicted of the murder of PSNI Constable Stephen Carroll in 2009.

Brendan McConville, 43, originally from Craigavon had been serving a 25-year sentence and 23-year-old John Paul Wootton from Lurgan received a 14-year jail term.

Their appeal was heard in Belfast High Court last year by three senior members of the judiciary, including Northern Ireland's Lord Chief Justice, Sir Declan Morgan, and their ruling was delivered this morning.

Constable Carroll was shot dead when he responded to a 999 call in a Lurgan estate five years ago.

The Continuity IRA claimed responsibility for his murder and he was the first PSNI member to be murdered by paramilitaries.

During the appeal, defence lawyers had challenged the evidence given by one witness during the original trial.

They described the testimony of the person known as "witness M" as "farcical".

He was known to his own family as a Walter Mitty character, who was a compulsive liar, they had said.
