A just-published opinion poll of Spanish attitudes suggests 70% of Spaniards support the country's continued membership of the euro zone, compared with 19 % who oppose it. Eighty-one per cent think Spain will remain in the common currency, while 6% think it will leave and 11% don't know.

The poll shows 90% of people are very concerned, and a further 7% concerned, about high unemployment, the chief source of crisis-related anxiety.
