Mr Gilmore’s book will be released next month and refer to controversial matters, including his resignation as party leader, Labour in crisis in power and future risks that could derail the recovery.

Senior Labour sources are believed to be nervous about the book’s release, particularly any reference which might leave the party or current leader Joan Burton in a bad light.

The book will be released by Merrion Press and is titled Inside the Room: the Untold Story of Ireland’s Crisis Government.

A description of it on Amazon states: “March 2011: Enda Kenny and Eamon Gilmore have just formed a coalition Government between Fine Gael and Labour.

“Ireland’s banks are broken, unemployment is heading for half a million, the public finances are in deficit, international lenders rate Ireland as junk and the country is in an IMF bailout.

“As Tánaiste in the new Coalition, Eamon Gilmore was at the heart of every major economic decision taken during his terms and as the minster for foreign affairs and trade was primarily responsible for restoring Ireland’s international reputation and trade connections.”

Mr Gilmore was forced to resign as party leader after last year’s local elections where Labour saw support plummet to just 7%, just over a third of that in the general election. He was replaced by Ms Burton.

The Dun Laoghaire TD was facing two motions of no confidence as leader from his party.

Mr Gilmore has said he will not be seeking reelection. His memoir is pencilled for release on October 26, shortly after the Coalition unveil their budget which Labour hopes will boost support with voters. But the memoir may reveal some uncomfortable truths for the party, as its pre-release summary suggests:

“In his extraordinary political memoir of these dramatic and turbulent times, Eamon Gilmore writes frankly about the political price the Labour party has paid for some of their choices, reflects on the circumstances that led to his own resignation and assesses the prospects for Ireland’s continued recovery, including the risks that could yet blow Ireland’s recovery off course.”

Despite Mr Gilmore’s resignation, there has been praise in how he ensured the Coalition held the same-sex marriage referendum.
