Everyone should co-operate with the Police Ombudsman, David Cameron has said after an MP called for families to receive "truth and justice" on the 20th anniversary of the Loughinisland massacre.
Speaking during Prime Minister's Questions, SDLP MP Margaret Ritchie said the families of the six men murdered in the notorious Heights Bar shooting as they watched the World Cup have never received truth and justice.
"Only two weeks ago, the police ensured that the Police Ombudsman's investigation was stalled. Does the Prime Minister agree with me that all UK police services must co-operate fully with their oversight authorities both to the letter and the spirit to ensure that families that I represent in Loughinisland receive truth and justice," she said.
Mr Cameron replied: "I agree with her that everyone should co-operate with the Police Ombudsman and I believe the Police Ombudsman system in Northern Ireland is actually now a model that other countries are looking to follow."
