Sean McGovern, 40, has pleaded guilty to two charges of directing the activities of a criminal organisation

McGovern, who was injured during the attack at the Regency Hotel in 2016, was previously named as "a significant figure" with a "leadership role" in the Kinahan cartel

Ms Justice O’Connor said that the court was entitled to make inquiries, as the information received so far was “scant, to say the very least”.

On May 29th last, when McGovern arrived in Dublin and was first brought before the court, Mr Callanan said he was reserving his position on the legality of the process and the jurisdiction of the non-jury court.
