Bertie Ahern will face questions about his economic record at the Banking Inquiry today.

The ex-Fianna Fáil leader, who served three terms as Taoiseach, is due to give evidence during the afternoon session from 2:30pm.

Among the questions he is is likely to be asked is whether he had any inkling that a major financial shock was coming, and if that might have influenced his decision to step down.

Mr Ahern was a TD from 1977 until February 2011 and held several senior positions in government, including that of finance minister.

He succeeded John Bruton as Taoiseach in June 1997, and continued to serve until his resignation in May 2008.

Banking Inquiry chairman Ciaran Lynch said: "Mr Ahern will be questioned on the nature and effectiveness of the operational implementation of the macro-economic and prudential policy; the appropriateness of the expert advice sought, quality of analysis of the advice and how effectively this advice was used".

He is also due to be quizzed about the effectiveness of the Oireachtas in scrutinising public policy on the banking sector and the economy - as well as the appropriateness of the advice from the Department of Finance to government.

The inquiry will also hear from the former Attorney-General Paul Gallagher this morning, who was in government buildings on the night of the guarantee.

Newstalk.com's political editor Shane Coleman told Breakfast he is expected to apologise for what his government got wrong.
