BRUSSELS (Reuters) - European Central Bank President Mario Draghi said on Thursday that negotiations with Britain on changes to its relationship with the European Union must preserve the "extraordinary achievements" of the euro and the EU's single market.

Draghi was responding to questions by two senior European Parliament members who urged him to take a stance on efforts by British Prime Minister David Cameron to secure recognition that the EU is a union with more than one currency.
