IBRC inquiry: The main players
Mr Justice Brian Cregan - The High Court judge was the third such legal figure appointed to examine matters relating to IBRC transactions.
He took up the role in July after Mr Justice Daniel O'Keeffe stepped down for personal reasons. Mr Justice Cregan is understood to have directed his officials to contact the Taoiseach's office last Thursday outlining his concerns. Following a request from Mr Kenny's officials, Mr Justice Cregan put his concerns in writing, which was received by Mr Kenny last Friday.

As the Government's most senior legal adviser, Ms Whelan would have been consulted over the terms of reference for the Commission of Investigation. Questions are being asked as to whether she raised any legal concerns over confidentiality and privilege.
