Greek Finance Minister Yanis Varoufakis announced his shock resignation this morning - only hours after the heavily-indebted country delivered a resounding 'no' vote on an international bailout package that plunged its future in the eurozone into further jeopardy.

Varoufakis claimed that during victory celebrations in Athens after the 'no' campaign won with a staggering 61 per cent of the vote, he was made aware that European Finance Ministers no longer wanted him to take part in talks on Greece's future.

Announcing his immediate resignation in a blog post that ended with Varoufakis claiming he will 'wear the creditors' loathing with pride', he revealed that Greece's Prime Minister Alexis Tsipras had judged that his leaving the job 'might help achieve a deal'.

Yesterday Greece overwhelmingly rejected Europe's latest bailout package, plunging the country's future in the eurozone into jeopardy.

Germany immediately played down the significance of Varoufakis's resignation after the outgoing finance minister was pictured riding around Athens on his motorcycle both last night and yesterday morning

'It is not about people but rather positions,' Chancellor Angela Merkel's spokesman Steffen Seibert said.

With Greek banks running out of cash and facing the danger of collapse within days without new aid, the government in Athens is racing against the clock to facilitate negotiations on a new bailout program.

Despite his frequent clashes with creditors in negotiations over the past few months, Varoufakis' resignation comes as a huge shock - especially coming so soon after the historic 'no' vote.

But the Finance Minister - who rose to fame and infamy this year for his informal image among stuffy European finance ministers, his abrasive negotiation style and his acerbic attacks on austerity - appeared to suggest that his immediate departure was in Greece's best interest.

This morning Spanish Economy Minister Luis de Guindos said his government is ready to talk about a third Greek bailout.

De Guindos told a press conference in Madrid after the government's economic team met to discuss Greece's referendum result that everyone wants Greece to 'stay in the euro.'

However, he said 'the rules for the euro remain the same as they were two days ago...I don't contemplate in any way Greece leaving the euro,' he said.

The minister conceded the situation now was probably the most complex since the euro launched in 1999 but that the currency's irreversibility would be reaffirmed at the meeting of eurozone finance ministers tomorrow
