David Drumm is due to appear before a Boston court on Monday where it is expected that matters relating to his possible voluntary return to Ireland will be discussed.

Mr Drumm's lawyers late yesterday requested a special conference before the court.

The judge presiding over his extradition matter, Judge Donald Cabell, agreed to the request for a conference before the court, also involving the US Attorney.

It's expected that Mr Drumm's lawyers will put forward a proposal which would involve him agreeing to return to Ireland on a voluntary basis.

It is understood various details are still under discussion and the exact nature of the conference was not set out in the legal documents filed yesterday.

Currently Mr Drumm is fighting a request from the Irish Government to extradite him to face 33 charges before the Irish courts relating to his time in charge at Anglo Irish Bank.

The extradition matter is due to be heard before the District Court of Massachusetts in Boston on 1 March.

Mr Drumm has twice been refused bail and has been in detention in the US since his arrest at his Wellesley home in early October.

He is currently appealing that decision and has claimed that he is being subjected to "intolerable and inhumane" conditions where he is being held.

Mr Drumm had offered a series of bail conditions if released in the US, including being placed under house arrest, wearing an electronic ankle bracelet, surrendering his family's passports and offering the homes and substantial cash bonds of a number of acquaintances as security.

His brother Kenneth Drumm this week said that David Drumm would return to Ireland if the Director of Public Prosecutions would guarantee not to oppose a bail request before the Irish courts.

Any such deal the DPP may consider however could be overruled by a presiding judge as they act independently of the DPP.

Mr Drumm faces 31 charges in relation to his role in the Maple 10 transaction, where ten individuals were each loaned €45million to secure Anglo's tumbling share price. 

He also faces two charges in relation to the back-to-back transactions with Irish Life and Permanent, designed to bolster the bank's books.
