The warning came as the yields on Spanish 10-year bonds spiked to 6.7pc, pushing the “risk premium” over German Bunds to a post-euro high of 540 basis points. The IBEX index of stocks in Madrid fell 2.6pc, the lowest since the dotcom bust in 2003. Chaos over the €23.5bn rescue of crippled lender Bankia has led to the abrupt resignation of central bank governor Miguel Ángel Fernández Ordóñez, who testified to the senate that he had been muzzled to avoid enflaming events as confidence in the country drains away.

Spain is going to bring the Euro project crashing down, not Greece and the exposure of UK banks to Spanish debt is considerable. Still, NO bank is too big to fail so time to let the free market sort it all out.
