Sinn Fein MEP Matt Carthy is calling on all parties across the Island of Ireland to set out their policies on a United Ireland.

The Midlands North-West MEP says the impact of Brexit is making a referendum on a United Ireland a much more real prospect.

He’s welcomed Fianna Fáil leader Micheál Martin’s promise to publish a twelve point plan on strengthening economic, political and educational links between the Republic and Northern Ireland.

"We want everyone to be involved in the conversation," he said.

In an interview with the Irish Times, Mr Martin said a united Ireland could operate along the lines of the current set up, but with the roles of Dublin and London reversed.

Speaking to The Pat Kenny Show earlier this week, he said there is no point in discussing the possibility of a referendum on the issue without examining how it might work.

“Northern Ireland for too long was governed by what I would term an ugly majoritarianism which was inherently sectarian,” he said.

“We don’t want to replace that with something else so in my view this has to be evolutionary [...] the real issue is, let’s make sure that this is developing peace, harmony, consensus.”
