Greece’s creditors have begun arriving in Athens to start technical discussions on a third euro bailout deal.

The negotiators were originally expected to arrive last week, although a spokesperson has said that there is no reason for the delay. Talks have just begun but high level talks are not due to start until early next week.

Ex-finance minister Yanis Varoufakis recently told a group of investors in London that he had commissioned a small team to work on a contingency plan, should the the European Central Bank (ECB) decide to cut off emergency funding to the Greek financial system. According to Greek newspaper Kathimerini the plan would involve copying online tax codes in order to introduce a parallel payment system if the banking system was closed down, which would have seen the return of the drachma.

“The context of all this is that they want to present me as a rogue finance minister, and have me indicted for treason. It is all part of an attempt to annul the first five months of this government and put it in the dustbin of history.” Varoufakis told the Daily Telegraph.
