Fianna Fáil leader Micheál Martin has called on the Government to publish the Referendum Commission's report on the recent referendums, ahead of the vote on the fiscal treaty on 31 May.
In a statement, Mr Martin accused the Government of taking a rushed, high-handed and dismissive attitude to the debates in recent referendums.
His comments came after a leaked report by the Referendum Commission said that it did not have enough time to do its job properly.
The commission was set up to promote public awareness of the votes on judges' pay and Oireachtas inquiries last October.
Taoiseach Enda Kenny has said the Government was confident the Referendum Commission will do its job to explain the fiscal treaty to people ahead of next month's referendum.
