The Dutch EU presidency is working on a plan to ease the migrant crisis by which a core group of member states would accept up to 250,000 refugees coming from Turkey in return for sending back the migrants that now arrive by the hundreds of thousands in Greece.

The leader of the Socialist PvdA party, a key partner in the government of Prime Minister Mark Rutte, told De Volkskrant paper Thursday that current EU plans were not working because of intransigence of many member states refusing to take refugees. Instead, Diederik Samson said a core group of nations should be willing to accept a set number of refugees coming from Turkey, if the other migrants can be sent back.

Samson said that once Turkey gains the full status as 'safe country' for migrants to be returned to, returns could happen speedily.

Even if the core group of EU nations would voluntarily accept the refugees, the 28-nation EU as a whole would have to bear the financial burden, he said.
