MI5 'planned to blow up Sinn Féin HQ in Dublin'

The British Security Services plotted to blow up Sinn Féin's Dublin headquarters during the height of the Troubles, a former undercover police officer claimed today.

An IRA informer was asked to place the bomb in the offices on Kevin Street in the summer of 1971, according to George Clarke, a retired Royal Ulster Constabulary Special Branch Detective Sergeant.
