(Reuters) - Ireland is in talks about tapping emergency funds from the European Financial Stability Facility, euro zone sources said on Friday, but Ireland said it had not formally applied for any European Union aid. The process of getting support from the EU requires a formal application from a euro zone government, that has to be assessed by the European Commission and the European Central Bank and approved by euro zone finance ministers. http://www.reuters.com/article/idUSTRE6AB32F20101112
