Former Anglo Irish Bank CEO and chairman Sean Fitzpatrick has been directed to appear before the Oireachtas Banking Inquiry on July 29, it emerged this evening.
His successor David Drumm, who is exiled in the US, has also been directed to appear on the same date along with other former Anglo executives Willie McAteer and Pat Whelan.
Under the powers granted to it, the Inquiry can compel witnesses to appear before it.
Mr Drumm, however, is unlikely to attend given he is now based in the US, but all other Anglo bosses who are living in Ireland are expected to appear.
"We haven't had any refusal from anyone at this stage," Chairman Ciaran Lynch said this evening.
It has also emerged that Taoiseach Enda Kenny and Tanaiste Joan Burton will appear before the Inquiry on July 23 along with Richard Bruton and Pat Rabbitte to discuss their party's economic policies in the run up to the 2007 General Election.
Former Taoiseach Bertie Ahern has also confirmed he is to attend the Inquiry on July 16 as is his former Attorney General Paul Gallagher SC. Mr Gallagher was in office on the night of the Bank Guarantee in September 2008 and the November 2010 Troika Bailout.
Mr Ahern's successor Brian Cowen will appear on two separate days, July 2 and July 8.
