A “mesmerisingly complex” scheme devised by bankrupt businessman Seán Quinn and members of his family to put multi-million assets beyond the reach of the former Anglo Irish Bank and “to feather their own nests” has been described by a judge as the largest and most devious seen to date in the Commercial Court.

The High Court has found bankrupt businessman Sean Quinn, his son and nephew to be guilty of contempt of court orders restraining him and his family from moving international assets.
