We know from the Fennelly commission that the former Garda Commissioner, Martin Callinan, had a close relationship with the former Secretary General of the Department. There were between 30 and 40 texts per month between the two, which works out at one a day. We know Ken O'Leary was almost always sent the same text. Was the level of contact enjoyed between Martin Callinan and Brian Purcell replicated between Nóirín O'Sullivan and Noel Waters?
