A member of the Government who voted No in the referendum which rejected the Nice Treaty is to be quizzed by the Taoiseach Bertie Ahern.
Minister of State, Mr Eamon Ó Cuiv, a grandson of former President and Taoiseach Eamon de Valera, said he had voted against the treaty "as a citizen" because European bureaucrats were seeking too much power.
But he said that as minister he accepted Government policy.
Mr Ahern, who has underscored his own disappointment at the 54 per cent referendum vote against the treaty, and has been embarrassed by the outcome, is to seek an undertaking from Mr Ó Cuiv that he will not publicly oppose any Government policy.
A spokesman for the Government said it was a matter for Mr Ó Cuiv to reconcile his private concerns with his role as a minister.
Mr Ahern is spending the weekend contacting fellow European leaders for discussions about the consequences of the Irish vote ahead of an EU summit next week.
