Specifically, five separate polls show New Democracy leading by a margin of 0.5 to 5.7 points. This would put the group ahead of the radical left wing Syriza party that opposes the terms of the second bailout signed with the "troika" (name given to the combination of the EU, the IMF and the ECB). "The lead is only slim and could change before the elections on June 17th however this is looking very good for the Eurozone as it shows that Tsipras' promises of rejecting austerity while staying in the euro are starting the wear thin with the Greek public and with around 85% opposed to leaving the euro we could see New Democracy's lead grow," said Alpari analyst Craig Erlam.However, concerns about Spain were also in focus today after the government was asked for €19bn in aid from troubled financial institution Bankia in order to strengthen its solvency.
