British and French interior ministers agreed on Tuesday to develop cooperation “now and when the United Kingdom leaves the EU” to address challenges posed by flows of migrants to the European Union. Britain’s new interior minister, Amber Rudd, came to Paris to meet her French counterpart, seeking assurances on a deal which allows Britain to make border checks in Calais and keep thousands of would-be migrants and asylum seekers in France. The meeting came days after French presidential contender Nicolas Sarkozy said Britain should deal on its own territory with migrants camped in the northern town, joining similar calls by Alain Juppe, also a conservative presidential candidate. Officials say there are about 7,000 migrants sprawled across the area known as the “Jungle” north of Calais, with the aim of many to reach Britain illegally through the Channel Tunnel. Non-governmental organizations put the number at over 9,000.
