Taoiseach Micheál Martin has suggested Sinn Féin may set back the cause of Irish unity by aligning itself with Scottish and Welsh pro-independence parties.

Mr Martin questioned whether Sinn Féin was on the right strategic track after the party signed a memorandum of understanding with the SNP and Plaid Cymru to put pressure on the UK government to call unity referendums in Scotland, Northern Ireland and Wales.
