One of the big talking points over the past few days has been on freedom of movement - the four freedoms of goods, services, capital and labour that come with European Union membership. Prime Minister Theresa May has insisted that free movement will cease at the end of March 2019 when Britain leaves the EU. And one of the places seriously affected by that change will be Ireland, where the border between the North and the Irish Republic will become the only land border between a non-EU UK and the other 27 member.
