A lawyer representing families of the Bloody Sunday victims has complained to the chairman of the Saville Inquiry about the abusive language used by former British Prime Minister Edward Heath.
Mr Heath has twice complained about questioning from Michael Lavery, QC, and accused the lawyer of using obscene and offensive language.
He has also refused to answer what he called hypothetical questions.
This afternoon, Mr Lavery told tribunal chairman Lord Saville that he felt insulted by Mr Heath's abusive language and that it should have reminded the former British PM that is was inappropriate to abuse counsel.
Lord Saville said he would bear the complaint in mind.
Also this afternoon, Colonel Roy Jackson, the commander of the Royal Anglican Regiment in Derry on Bloody Sunday, said the Parachute Regiment should not have been sent into the Bogside in armoured cars because it only served to drive rioters back into the main body of the crowd before they could be arrested.
The paratroopers were sent into the IRA-controlled area on January 30, 1972, to arrest rioters at the fringes of a Catholic civil rights march.
However, the soldiers ended up killing 13 unarmed civilians when they opened fire on the marchers.
