The European Union's rules on asylum, which state that requests be handled by the country where asylum is first claimed, are splitting Europe, the prime minister of Bulgaria, which holds the EU's rotating presidency, said on Monday. Nationalist-minded, eurosceptic governments in Poland and Hungary have refused to take in a single asylum seeker under a scheme to have each member state host a number of refugees to ease pressure on the main sea gateways of Greece and Italy. "The Dublin Regulation does not work the way we want it to," said Borissov, referring to one of the main EU laws on asylum.
