Sinn Féin chief negotiator Mr Martin McGuinness is today today to deny claims he was preparing an attack in Derry on Bloody Sunday when he submits another statement to the Saville Inquiry.
It has been alleged that Mr McGuinness and another member of the Provisional IRA had detonators for 16 nail bombs that were going to be used in attacks. However, it is claimed, the plan to launch the attacks was pulled.
In a statement to the Saville Inquiry, Mr McGuinness has already admitted to having been a senior member of the IRA in 1972.
He is now expected to deny former IRA man Paddy Ward's claim, insisting he did not know the man making allegations against him.
He is also expected to challenge the claim, which is contained in a biography of him by journalists Mr Liam Clarke and Ms Kathryn Johnston.
The inquiry is currently sitting in London taking testimony from a number from soldiers who were on duty on Bloody Sunday.
