Taoiseach warns Opposition that IBRC inquiry could be long-running and expensive

Enda Kenny has warned opposition leaders that an IBRC Commission of Investigation could end up becoming as long-running and expensive as a Tribunal of Inquiry.

The warning comes in a private letter outlining the legal options for reviving it.

The letter also outlines plans to bring forward the investigation into the sale of SiteServ to businessman Denis O'Brien - which would still take almost 12 months.

However, there is also a risk that it could result in legal action regarding the decision to single out the SiteServ case.
