Legislation has been published which would give extra powers to the inquiry into IBRC and the sale of SiteServ.
The Cregan Commission has faced a series of problems since it started, particularly in relation to legal privilege over crucial documents.

Social Democrats TD Catherine Murphy, said that she hopes the legislation is robust enough to allow the inquiry to finish its work.

"I'm presuming that will proof it against other issues that might arise that haven't been thought about."
