Head of the Eurogroup Jeroen Dijsselbloem said on Sunday that the outcome of the referendum is "regrettable".

"I take note of the outcome of the Greek referendum. This result is very regrettable for the future of Greece. For recovery of the Greek economy, difficult measures and reforms are inevitable. We will now wait for the initiatives of the Greek authorities. The Eurogroup will discuss the state of play on Tuesday 7 July," he said.
