Should the government renegotiate the Le Touquet accord?

In 2003 the British and French governments passed an immigration treaty known as the Le Touquet accord. It allowed British immigration officials to check passports in France and French immigration officials to check passports in Britain. Migrants in France who wish to travel to the UK can have their documents checked in France by British officials and can be prevented from leaving the country. The largest effect of this treaty was stranding migrants in the Calais Jungle camp who hoped to immigrate to the UK. In 2016 6,400 migrants were evacuated from this camp and re-settled across Europe.
