Eurogroup head Jeroen Dijsselbloem on Saturday said Greece's decision to hold a referendum over the future of its bailout programme was a "sad" decision that shut the door to further talks.

"The Greek government has apparently rejected our last proposals... that is a sad decision for Greece because it has closed the door for further talks where the door was still open in my mind," the Dutch finance minister said as he arrived for talks with his eurozone counterparts.
