Greek government spokesman Elias Mossialos said on Monday that any solution decided must be legally secure, adequate and not high-risk, and must not harm Greece's fundamental rights in the EU core. In a statement on the ongoing deliberations over the Greek debt and the crisis in the eurozone, Mossialos added that no issue has been institutionally put forward for a further increase in the bond swaps than that originally foreseen in the July 21 eurozone summit agreement.

Mossialos also said that there is no issue of nationalising any banks, beyond that of Proton Bank announced earlier in the day, which he said was a "special case".

The spokesman further described as "positive" references by German chancellor Merkel and French president Nicolas Sarkozy on the need for recapitalisation of banks, where needed, to boost the economic governance in the EU, and intimated that Greek prime minister George Papandreou will hold a series of briefings with the opposition party leaders.
