SDLP leader Mark Durkan has described members of Britain's MI5 spy agency as "para-terrorists".
Mr Durkan claimed today that the undercover internal security outfit had been involved in numerous terrorist crimes in the North, including the murder of innocent civilians in collusion with loyalist paramilitaries.
The SDLP leader was speaking during a House of Commons debate in London about moves to give MI5 a greater role in security in the North.
He said the SDLP could not accept British government assurances that the spy agency's past misdeeds would not be repeated.
Mr Durkan claimed Britain was in denial about its ugly role in the North and had acted precisely and deliberately to make sure that the truth about its activities would never emerge.
