The prospect of a rescue for Spain’s economy, which is twice the size of that of Ireland, Greece and Portugal combined, is sowing deep concern in world financial markets.

“I am not delivering a message of confidence just because I want to but because of concrete facts,” the prime minister said in an interview with Catalan radio RAC 1.

Asked if he could rule out a rescue he replied: “Absolutely.”

Zapatero said there was “no scenario” under which a rescue of Spain could be envisioned.

“Those who push this idea are not contributing to calm,” he said.
