 In the document, Hurst alleged that up to 25 IRA operatives had been involved in the ambush, both directly and indirectly, According to Hurst, about one quarter of them were British agents.and that British agent and IRA intelligence officer Stakeknife had been aware of the plot as he was responsible for gathering the information that had led to the ambush.Hurst's evidence led the chairman of the Ulster Unionist Party North Down Association (and former RUC officer) Colin Breen to suggest that, had the information been passed on by the British Intelligence Corps to the RUC or Garda Síochána, the double killing could have been prevented.
