TAOISEACH Enda Kenny last night piled the pressure on Gerry Adams over the latest allegations of the Sinn Fein president's involvement in IRA executions.
Mr Kenny said it was galling to listen to Sinn Fein talk about transparency in politics in light of the serious accusations made again Mr Adams.
And a Fine Gael TD called on Mr Adams to make a formal statement to the Dail about the claims that he was a senior figure in the Provisional IRA.
Mr Adams is currently away in the United States but Sinn Fein deputy leader Mary-Lou McDonald became the latest party figure to defend her leader.
The Taoiseach raised the issue of Mr Adams's IRA past after further allegations of his role from a one-time close ally.
Last weekend, former IRA bomber Dolours Price described how Mr Adams ordered her to ferry captives, including Belfast mother-of-ten Jean McConville, across the Border to be murdered.
She also implicated him in ordering the IRA bombing campaign in Britain in the 1970s.
When Mr Kenny was asked by Ms McDonald about "transparency" in Health Minister Dr James Reilly's decisions on primary healthcare locations, the Taoiseach pointed to the allegations against Mr Adams.
"It astounds me that you have the gall to stand up in this House in view of the statements made by one of the Price sisters about the leader of your own party," he said.
"We have the Deputy from Sinn Fein making an articulate point here about clarity and about transparency and she should also add in truth."
The Sinn Fein president is coming under intensifying pressure to explain his IRA past. Fine Gael's Tom Barry said he wanted to see Mr Adams respond in a statement to the Dail. He asked Ceann Comhairle Sean Barrett what procedures were in place to allow such a statement.
Fianna Fail leader Micheal Martin has also called for Mr Adams to respond.
Fine Gael's parliamentary party chairman Charlie Flanagan said the Louth TD had to make a Dail statement this week on the claims that he was personally involved in ordering IRA bombings and executions.
Mr Flanagan said Mr Adams had to answer the charges about the "abduction, murder and disappearance" of Ms McConville.
Defending Mr Adams, Ms McDonald said he was in the United States to attend the Clinton Global Initiative.
She said Mr Adams had "rejected again, as he has consistently rejected", the allegations made by Ms Price.
Ms McDonald added: "I think it is interesting that Fine Gael would use the statements of an opponent of the peace process in an attempt to undermine the leader of Sinn Fein.
"By her own admission, Dolours Price thinks that the peace process should be undermined, should be destroyed.
"The remarks attributed to Charlie Flanagan are a very obvious attempt by Fine Gael to distract from its own difficulties, in particular the clear dysfunction in the Health Department led by Fine Gael minister James Reilly."
