Mark Lundy's murder convictions have been quashed and he has been granted leave for a retrial by the Privy Council in London.
Lundy was convicted of murdering his wife Christine and daughter Amber in August 2000, and was sentenced to a jail term of at least 20 years.
His case was taken to the Privy Council and a three-day appeal hearing was held in June.
In its decision - released tonight - the Privy Council unanimously decided that Lundy's appeal should be allowed; that the convictions should be quashed; that Lundy should stand trial again on the charges of murder as soon as possible; and until then, and subject to any High Court decision on bail, Mr Lundy should remain in custody.
