The president of the European Council, Donald Tusk, appears set to tell EU leaders that Brussels is prepared to abandon the scheme that compels member states to accept quotas of refugees. Tusk will tell leaders at a summit on Thursday that mandatory quotas have been divisive and ineffective, and announce a six-month deadline for EU leaders to reach unanimous agreement on how to reform the European asylum system. In 2015, the EU passed a migration plan that called on each member state to take in a quota of refugees, but several eastern states balked at the plan.
