The Minister for Foreign Affairs, Charlie Flanagan, has met his UK counterpart to discuss ways Ireland can support the British government ahead of the UK's Brexit vote in June.
There are concerns at the knock-on effect on Ireland if Britain votes to leave the European Union.
Mr Flanagan said one of the biggest concerns regarding a positive result for the pro-EU side was voter turnout and ensuring that the electorate was fully informed of the issues so that they feel confident to take a stand either way.
Given Ireland’s comparably vast experience with referendums, the Foreign Affairs Minister advised the British Foreign Secretary it was important to engage at grass roots level with members of the public, including town halls and community groups.
Minister Flanagan also warned of complacency ahead of the vote.
He said: "There could well be an element of complacency as far as this campaign is concerned and that's why I'm here in London with 80 days to go.
"I will be encouraging members of the Irish community to become actively involved in the campaign."
