An Ex-IRA man who claimed Sinn Féin's Martin McGuinness handed out nail bombs to members of the paramilitary group on the morning of Bloody Sunday has been branded a liar by his former father-in-law.
In evidence to the Saville Inquiry last year, Paddy Ward said that Mr McGuinness, right, gave him detonators for 16 nail bombs on the morning of the Civil Rights march.
Mr McGuinness has strenuously denied the accusation, although he has admitted being the IRA's number two in Derry's Bogside on Bloody Sunday.
At yesterday's (Monday) hearing of the Saville Inquiry, Daniel McGilloway whose daughter was married to, but now separated from Paddy Ward rejected further evidence given by Mr Ward to the inquiry that after the shootings on Bloody Sunday, he (Mr Ward) had run through Mr McGilloway's home in the Bogside carrying a rifle and gone into the back garden, where he fired two shots at a military helicopter.
He said: "He did not come to our house that day at all and there is no question of my having locked the door behind him, as he suggests in his statement.
"You would not forget something like Bloody Sunday or a man with a rifle in your house," he added.
In a separate development, the inquiry was urged to determine the extent of former prime minister Sir Edward Heath's responsibility for the deaths of those killed on Bloody Sunday
Lord Gifford said: "By the end of January the choice was made to enforce the law with rigour. In the making of that choice, the prime minister played a decisive role."
Sir Edward "did not urge restraint", he said.
"Taking off the kid gloves, which Sir Edward Heath clearly authorised, and applying the law with rigour, as he clearly intended, was something which had a price and the risk was deliberately run," he added.
Earlier, the lawyer branded soldiers who opened fire on Bloody Sunday as a "death squad".
Lord Gifford is representing the family of James Wray (22), who was shot dead.
The shot which killed Mr Wray was "one of the defining moments of that day", he said.
The shot had not been fired out of a sense of being in danger, but deliberately to "get a kill", he added.
