A High Court judge has strongly criticised the continuing failure over months to make a decision whether accountancy firm KPMG should, in its capacity as former auditors to Irish Nationwide Building Society, be sued as a co-defendant in separate actions by State-owned IBRC against Michael Fingleton and other former directors of the society over €6bn losses.

A judge said he wants to be told by the end of October whether it is proposed to join accountancy firm KPMG, former auditors of Irish Nationwide Building Society, as a co-defendant in a legal action brought over €6bn losses at the society.

An application may be made to join accountancy firm KPMG as a defendant to a legal action arising from €6bn losses at Irish Nationwide Building Society.
