Greece’s new finance minister resigned because of ill health on Monday, throwing the government’s drive to soften the terms of an international bail-out into confusion days before a European summit, Reuters reported.

Vassilis Rapanos, 64, chairman of the National Bank of Greece, was rushed to hospital on Friday, before he could be sworn in, complaining of abdominal pain, nausea and dizziness. Greek media said he had a history of ill-health. The office of Prime Minister Antonis Samaras, who himself only took office last Wednesday following a June 17 election, said Rapanos had sent a letter of resignation because of his health problems and it had been accepted.

Samaras himself has only just emerged from hospital after undergoing eye surgery to repair a damaged retina. Both he and Rapanos had already said they would not be able to attend the June 28-29 European summit.

It was a worryingly chaotic start for the new government, formed after the second election in a month, which faces a rocky road in responding to huge domestic opposition to a harsh international bail-out in the face of steadfast European opposition to any watering down of its terms.

Only hours before Rapanos’s resignation, a hospital bulletin said he would be discharged on Tuesday. He had undergone a gastroscopy and colonoscopy, an official at the Hygeia Hospital told Reuters on condition of anonymity. The tests “showed everything is completely normal”, it said.

According to a source from one of the three parties in the new coalition government, Rapanos had been under heavy pressure from his family to turn down the stressful job because of his health problems.

Earlier on Monday the three party leaders had announced a trans-Atlantic road show to try to persuade sceptical lenders to give them more time to repay the country’s massive debt.

The medical problems of Samaras and Rapanos had also forced a postponement of the first meeting between the new government and Greece’s “troika” of international lenders, originally slated for Monday.
