The Sinn Féin president has claimed that the United Kingdom, as a union of four countries, is hanging by a thread.

Gerry Adams made his comments as Prime Minister David Cameron urged the people of Scotland to vote to stay in the UK in September's independence referendum.

His comments came as Sinn Féin activists gathered for the party's annual conference (ard fheis) in Wexford.
