Graham Dwyer has failed in his bid to overturn his conviction for murdering vulnerable child care worker Elaine O'Hara, almost eight years to the day he was found guilty by unanimous jury verdict.

President of the Court of Appeal, Mr Justice George Birmingham on Friday morning delivered the judgment of the three-judge court, dismissing all grounds of appeal including a claim by Dwyer's lawyers that the use of call data records at his trial should lead to a retrial.
