Scotland’s First Minister Nicola Sturgeon has said a second independence referendum is now “on the cards”.
The country rejected independence in the first poll in 2014, however Ms Surgeon said there are now grounds to hold another vote.
She said it would be “democratically unacceptable” for Scotland to be taken out of the European Union “against its will” and will now explore “all options”.
The people of Scotland voted in favour of remaining in the EU.
Secretary of State Theresa Villiers has said a referendum on a united Ireland would not be “justified or helpful” at present.
Taoiseach Enda Kenny has said “the implications for NI and relations will require careful consideration” following the UK's Brexit vote.
Northern Ireland’s leaders have been divided in their reactions to the United Kingdom’s decision to leave the European Union.
