EU and German officials said Spain faces supervision by international lenders after the deal to lend Madrid up to 100 billion euros (£80bn), contradicting Prime Minister Mariano Rajoy who insisted the cash came without such strings.

Cyprus, which is deeply exposed to Greece, strongly hinted that it may apply for an international bailout before the end of this month, both for its banks and for the state. It would be the fifth member of the 17-nation euro area to require assistance since the debt crisis erupted in Greece in late 2009.
