The full scale of debt writedowns approved by IBRC has been revealed. The Sunday Business Post claims that €1bn was written off for 40 customers.

The paper also claims the proposed commission of investigation into the bailed-out bank will examine its tax affairs.

During the week Enda Kenny called Government plans for an IBRC probe "right and proper". He also said he did not regret not calling for a full inquiry when the SiteServ controversy arose in April.

It is expected the IBRC investigation will look at deals involving a write down of €10m or more, and whether preferential low interest rates were offered to customers.
