Fine Gael has questioned whether the Dublin Docklands Development Authority remains solvent because of a land purchase involving Anglo Irish Bank.
This followed today's admission by the authority's CEO Paul Maloney that no interest has been paid since last June on the loan of nearly €300m to purchase the Irish Glass Bottle site in Dublin.
Mr Maloney told the Oireachtas Environment Committee that the authority was part of a consortium and was liable for just €26m.
But Fine Gael spokesperson Phil Hogan challenged the Minister for the Environment John Gormley to clarify whether the authority remains solvent.
He also said that there was an unhealthy relationship between the recently nationalised bank and the authority as two men were directors of both organisations at the time.
The Dublin site was bought for €412m in 2006 by a consortium headed by developer Bernard McNamara, but the authority has invested a 26% stake.
