State Papers 1987: Haughey warned that MI5 ordered his assassination

Records from his office while he was taoiseach in 1987 reveal that the UVF wrote to him to tell him that British intelligence also launched a smear campaign against him.
The loyalists claimed their organisation was used by MI5 and MI6, backed up by British Army special forces, from 1972 to 1978 and again in 1985.
