The search for an optimal solution for resolving the Greek debt crisis will continue, taking into account the interests of all parties,” Dmitry Peskov told reporters.

The phone call between Putin and Lagarde was not linked to any potential Russian help for Greece, he added.

The IMF said earlier yesterday that it was monitoring the situation in Greece and was ready to lend a hand if asked following a referendum that rejected the bailout conditions of international creditors.

Meanwhile, the Dutch prime minister Mark Rutte said Greece would have to accept deep reforms if it wanted to remain in the eurozone.

In a debate in parliament in the wake of Greece’s No vote, Mr Rutte said his government was unwilling to give any new funding to Greece unless it committed to reform.

“If things stay the way they are, then we’re at an impasse,” he said. “There is no other choice, they must be ready to accept deep reforms.”
