EU referendum as important for Ireland as Good Friday Agreement - Enda Kenny
Taoiseach Enda Kenny says a Brexit is the biggest challenge and greatest risk Ireland is facing and the outcome of the EU referendum would be "as important for Ireland as Good Friday Agreement".
He said the forthcoming poll was a "truly momentous decision".
The Irish premier was speaking during a visit to Ulster University in Belfast on Monday afternoon.
He said the decision was "as important for Ireland as the Good Friday Agreement".
Mr Kenny told a packed room that a Brexit is a vote which "we would very much wish to avoid".
"If the UK decides to leave the EU I will be the only person from these islands at the European council meetings," he said.
He said there would be "no voice" at the "top table" to speak for the UK and Northern Ireland if it votes to leave the EU.
Mr Kenny is due to meet Prime Minister David Cameron amid growing Irish concerns about the outcome of the June 23 referendum.
Enda Kenny last month urged Irish people living in Britain to vote Remain, saying the Republic would be one of the worst affected countries should the UK leave the European Union.
He warned custom controls could have to be set up at the Irish Republic's border with Northern Ireland in the event of a Brexit vote.
Speaking in London, Mr Kenny said Irish people make up a "substantial" part of the electorate and urged them to vote.
