The euro will have broken up before the end of this Parliamentary term, according to the bulk of economists taking part in a wide-ranging economic survey for The Sunday Telegraph.

• The Government will borrow almost £10bn less next year than the Treasury previously forecast, despite this weaker growth.

• Just as many economists think the Bank of England will not raise rates until 2012 or later as think it will lift borrowing costs this year.

But the conclusion on the euro is perhaps the most remarkable finding. A year ago or less, few within the City would have confidently predicted the
currency's demise. But the travails of Greece, Spain and Portugal in recent
weeks, plus German Chancellor Angela Merkel's acknowledgement that the
currency is facing an "existential crisis", have radically shifted
opinion.

Two of the eight experts who predicted that the currency would survive said it would do so only at the cost of seeing at least one of its members default
on its sovereign debt. Andrew Lilico, chief economist at think tank Policy
Exchange, said there was "nearly zero chance" of the euro
surviving with its current membership, adding: "Greece will certainly
default on its debts, and it is an open question whether Greece will
experience some form of revolution or coup – I'd put the likelihood of that
over the next five years as around one in four."

Douglas McWilliams of the Centre for Economics and Business Research said the single currency "may not even survive the next week", while David
Blanchflower, professor at Dartmouth College and former Bank of England
policymaker, added: "The political implications [of euro
disintegration] are likely to be far-reaching – Germans are opposed to
paying for others and may well quit."

Four of the economists said that despite the wider suspicion that Greece or some of the weaker economies may be forced out of the currency, the most
likely country to leave would be Germany.

Peter Warburton of consultancy Economic Perspectives said: "Possibly Germany will leave. Possibly other central and eastern European countries –
plus Denmark – will have joined. Possibly, there will be a multi-tier
membership of the EU and a mechanism for entering and leaving the single
currency. I think the project will survive, but not in its current form."

Tim Congdon of International Monetary Research said: "The eurozone will lose three or four members e_SEnDGreece, Portugal, maybe Ireland e_SEnD and
could break up altogether because of the growing friction between France and
Germany."

The recent worries about the euro's fate followed the creation last month of a $1 trillion (£691bn) bail-out fund to prevent future collapses. Although the
fund boosted confidence initially, investors abandoned the euro after
politicians showed reluctance to support it wholeheartedly.
