Sinn Féin leader Gerry Adams has said that he would be happy to debate with Micheál Martin on the EU fiscal treaty - along with all the other party leaders.
Deputy Adams was responding to a challenge from the Fianna Fáil leader who made the offer following the Sinn Féin TD's refusal to participate in the recent TV3 referendum debate.
In a statement today, Deputy Martin said as president of the leading party advocating a No vote, Deputy Adams should be willing to debate, and to outline what he believes a No vote would mean for Ireland.
Today Deputy Adams said he is prepared to debate other party leaders on the fiscal treaty "given the importance of this referendum to Ireland's future".
But the Fianna Fáil leader is calling for a one-to-one debate.
"He (Deputy Adams) simply refused to go on that TV3 debate and I am now giving him another opportunity to debate on a head-to-head basis, one-to-one, in relation to the treaty and the issues around the treaty," Deputy Martin said.
"And I think he should accept that."
