Teresa May visited Northern Ireland as Prime Minister for the first time yesterday and suggested that there will be a change to the current open border between Northern Ireland and the Republic if Ireland following the Brexit vote.
Although Theresa May has said that "nobody wants to return to the borders of the past" she also indicated that some change will be necessary.
"If you look ahead, what is going to happen when the UK leaves the European Union is that of course Northern Ireland will have a border with the Republic of Ireland, which will remain a member of the European Union," said Mrs May.
But we've had a common travel area between the UK and the Republic of Ireland many years before either country was a member of the European Union.
"Nobody wants to return to the borders of the past. What we do want to do is to find a way through this that is going to work and deliver a practical solution for everybody - as part of the work that we are doing to ensure that we make a success of the United Kingdom leaving the European Union - and that we come out of this with a deal which is in the best interests of the whole of the United Kingdom."
The Independent reports that North's First Minister Arlene Foster said the DUP wanted to see the free movement of people continue but warned that imigration is handled "in a very different way" while senior government sources in Dublin accepted some changes to the current 'invisible' border may have to occur but insisted a hard border was "not an option".
