Former Fine Gael leader Alan Dukes has criticised the Director of Corporate Enforcement for delays in its investigation into Anglo Irish Bank.

Speaking at the MacGill Summer School in Donegal, Mr Dukes, who is a Director of Anglo Irish Bank, called for the investigation to be concluded as soon as possible.

He criticised the Director of Corporate Enforcement for the way his investigation has been carried out.

Mr Dukes said he found it odd that the Director of Corporate Enforcement said he may be in a position to tell the DPP there is a legal case in November, after he announced last February there was a prima facie case for an investigation into the bank and after sending people into the bank in April to begin the inquiry.

Currently, Anglo Irish Bank is involved with three separate sets of investigations by the Director of Corporate Enforcement, the Financial Services Regulator and the Chartered Accountants Regulatory Board's complaints committee.
