Good Friday Agreement Internal Market Bill
 The Single European Act entered into force in 1987, an amendment to the Treaty aimed at strengthening European integration and creating an internal market.  This single market, known as the European Single Market, was created in 1993 the same year as the transformation of the EEC and related organisations in the European Union (EU).  But it is also true that the maritime border was literally created at the request of Johnson, who called for the lifting of former Prime Minister Theresa May`s backstop, which would have made such controls less likely by linking the entire UK to closer relations with the EU`s internal market and customs union, unless sea and land controls could be avoided. .
