Former Taoiseach Bertie Ahern returns to the witness box at the Mahon Tribunal this morning.
He is due to give two days of evidence at Dublin Castle.
With the Mahon Tribunal nearing a close, Bertie Ahern faces more questioning today and tomorrow about his financial affairs.
The inquiry is expected to focus in on the main allegation from Tom Gilmartin - that Mr Ahern received a bribe of £80,000 from developer Owen O'Callaghan in the 1990s - when he was Minister for Finance.
At the time Mr O'Callaghan and Mr Gilmartin were developing Quarryvale - which became the Liffey Valley Shopping Centre.
Both Mr Ahern and Mr O'Callaghan strenuously deny the allegation and have on many occasions stressed that no money passed between them.
The former Taoiseach's two days of evidence come as his party meets in Galway for a think-in.
