Should EU introduce migrant quotas?
EU leaders are to discuss controversial proposals by the European Commission for a quota system for migrants - to decide where those who have sailed to Europe should be settled.
More than 1,800 people have died already this year trying to cross the Mediterranean.
The UK could decide not to be a part of any such system and the Home Office said on Monday that the government would oppose a quota that was not voluntary.
