BRUSSELS, March 23 (Reuters) - Eurogroup chief Jean-Claude Juncker would welcome a meeting of leaders of countries using the euro to discuss Greece's fiscal woes ahead of the European Union's summit on Thursday, his spokesman said on Tuesday.

It's the first time that I hear about such a meeting. Mr Juncker is part of those member states that favours that (meeting) but thinks it should not be institutionalised, spokesman Guy Schuller said. (Reporting by Julien Toyer)
