In return for help in making the Channel Tunnel and the port at Calais more “secure”, France has agreed to monitor Britain's borders on its behalf. On the Italian frontier, meanwhile, French police are searching for migrants who have crossed the Mediterranean. As Carine Fouteau reports, interior minister Bernard Cazeneuve has taken on the mantle of Europe's new gatekeeper, at the risk of breaching European law.
At joint press conference with French president, Italian premier Matteo Renzi denied tensions over migrants at frontier town of Ventimiglia.
Around 300 migrants had been camping out for days in Ventimigila on the frontier, sparking tension between the two countries.
More than 100 migrants have begun a sit-in at the Vintimille frontier post where police reinforcements were sent to stop them entering France.
