Former Sinn Féin President Gerry Adams wants more information from BBC for defamation action against it

Former Sinn Féin President Gerry Adams wants the High Court to order the BBC to hand over more information he says he requires for a defamation case he is taking against the broadcaster.
He is suing the BBC claiming it defamed him when it falsely alleged he had sanctioned the killing of former Sinn Féin official Denis Donaldson who worked for decades as a spy for the British.
