Cameron: Euro needs single government to work properly

LONDON - A successful euro zone requires a single government if it is to work properly, British Prime Minister David Cameron said in a newspaper interview on Wednesday.
"There's nowhere in the world that has a single currency without having more of a single government," Cameron told Britain's Daily Mail.
"Making sense of the euro for me would mean that those euro zone countries would have to have much more coordinated economic policy, much more coordinated debt policy," he said.
Cameron, who opted out of a new European economic pact late last year, advocated Britain's position outside the euro and its ability "to do things to ourselves, for ourselves, by ourselves.
