The IRA, which carried out a series of bombing attacks in England before the opening of the second World War, had been infiltrated by “ultra-conservative sections of the British secret service”, Seán Lemass believed.
Lemass accused the IRA of scuppering attempts by the Irish government to open a line of dialogue with the Stormont government over the issue of partition.
