The head of the Eurogroup Jeroen Dijsselbloem said on Thursday that if Greeks vote "No" on Sunday, it could mean that Greece have to leave the Eurozone. He added that Greeks should not expect better conditions if they vote "No".

"One illusion must be swept from the table: that if the outcome is negative then everything can be renegotiated and you will end up with an easier and more attractive package," Dijsselbloem said.

"If people say they don't want that, there is not only no basis for a new programme, there is also no basis for Greece in the euro zone," the head of the Eurogroup pointed out.

Dijsselbloem noted that Eurozone countries will help Greece if Greeks vote "Yes" on Sunday.
