European leaders could hold a special summit in early March to discuss the euro and to push for a comprehensive reform package in the currency bloc, Reuters quoted euro zone government sources as saying on Friday. It was not clear whether the summit being considered would involve leaders of euro zone countries or the whole European Union, said the sources, who asked not to be identified. Holding such an event could counter allegations of a lack of urgency among European leaders, who meet next Friday to talk about energy but are not currently scheduled to take decisions on measures to resolve the euro crisis until a summit in late March. "We would be happy to have such a meeting because preparations on a comprehensive package are not going as rapidly as some would like, let's put it that way," said one source. "There is a sense that the momentum and urgency has decreased, partly because the market pressure appears to have diminished, even if that is not really the case," added the source. "We must not become complacent." EU finance ministers agreed last week to take their time over beefing up the euro zone's rescue fund, in a go-slow approach championed by Germany which could test the patience of investors spooked by the debt crisis. European Commissioner Jose Manuel Barroso warned earlier this week, ahead of a meeting with German Chancellor Angela Merkel, that there was a risk of "procrastination". This was seen as a reference to Berlin's rejection of his proposals to boost the European Financial Stability Facility (EFSF). -- SPA
