May and Macron will announce bilateral agreements on student exchanges, twinning of cities and other cultural exchanges. Theresa May appeared to admit on Monday that the deal needed to be reviewed as she pledged to defend border controls, arguing they benefit France as much as the UK. On 15 December 1993, Belgium, France and the United Kingdom signed a tripartite agreement. The agreement allowed Belgian officials to carry out immigration checks at London Waterloo International station and British officials to carry out immigration checks at Brussels South station for passengers travelling on direct Eurostar trains between London and Brussels.  The tripartite agreement was then concluded in the United Kingdom through the Channel Tunnel (Various Provisions) Order 1994, in France by Law No. 1994. 94-403 of 20 May 1994 and Decree 98-172 of 10 March 1998 and entered into force in Belgium by law of 29 August 1997.  Emmanuel Macron, the newly elected French president, promised during his election campaign to renegotiate the Le Touquet agreement, which allows British border guards to carry out checks in France. The agreement, also known as The Treat of Touquet, allows British immigration officers to carry out border checks in northern France rather than in Dover. THE MINISTER – Yes, it is; the agreement of Le Touquet…
Q. – It is the Le Touquet agreement that places the British border here in France…. In 1991, the Sangatte Protocol was signed between France and the United Kingdom, an agreement that provided for the establishment by France of border checkpoints at the Eurotunnel Folkestone Terminal in Cheriton, Kent, and the establishment by the United Kingdom of border checkpoints at the Eurotunnel Calais terminal in Coquelles, France. The Sangatte Protocol is rather known as the protocol between the Government of the United Kingdom of Great Britain and Northern Ireland and the Government of the French Republic on border controls and police work, criminal justice cooperation, public safety and mutual assistance in relation to the Channel link.  The Sangatte Protocol came into force in France by Decree 93-1136 of 24 September 1993 and, in the United Kingdom, by the Channel Tunnel (International Arrangements) Order 1993.  During last year`s French election campaign, Macron said he wanted to renegotiate or denounce the 2003 Le Touquet agreement, which introduced French border controls in Britain and British controls in Calais. On 4 February 2003, France and the United Kingdom concluded the Treaty of Le Touquet (formerly known as a treaty between the Government of the United Kingdom and the Government of the French Republic on the organisation of border controls at the seaports of the two Channel and North Sea countries).    This agreement provided for juxtaposed controls on a number of ferry routes across the English Channel.
The treaty was put into force in France by Law No. 2003-1368 of 31 December 2003 and, in the United Kingdom, by the Nationality, Immigration and Asylum Act 2002 (Juxtaposed Controls) Order 2003.  It is difficult to resolve sharp differences over the British border with France.
