The latest offer from Turkey is:
Turkey takes back a non-Syrian migrant who has crossed into Greece and 'replaces' him/her by sending Greece a Syrian refugee, on a one-for-one basis
Plus
The EU pays 6 billion Euros to Turkey
Plus
The EU agrees to permit Turks to travel visa-free within the EU from June 2016 (instead of previously agreed 1 Oct 2016)
Plus
Turkey's full EU membership is fast-tracked.
So, does the EU accept Turkey's deal or say 'No Deal'?
