European leaders have agreed in principle to work for thecreation of a single banking union in which member states wouldjointly back their banks as a means of shoring up the Europeanfinancial system.

The leaders sidestepped the question of whether or not theybelieved Spain would seek European aid.

"It's up to the Spanish to decide on their own what to do,"Hollande said.

"To put forward an aid plan with the conditions attachedwhich would have to be clarified or not, if they don't need it."

Speaking to reporters at the margins of the meeting, SpanishPrime Minister Mariano Rajoy said he would seek the bestdecision "without ruling out any possibility".
