The leaders of the 17 countries that use the euro, plus six others, have tentatively agreed to a new treaty that enforces stricter budget rules seen as crucial to solving Europe's debt crisis and holding the currency-bloc together. The effort by Germany and France to persuade all 27 European Union countries to agree to treaty changes failed, in large part because of Britain's refusal to give up some powers. Following marathon all-night talks, the 23 decided to back a new treaty with strict oversight over national budgets, as they try to convince markets that the euro has a future. An agreement on fiscal discipline is considered a critical first step before the European Central Bank, the International Monetary Fund and others would commit more financial aid to help countries like Italy and Spain, which have large debts and unsustainable borrowing costs. ECB President Mario Draghi praised the tentative deal as a good result for the eurozone. The immediate market response was lukewarm, with stock markets in Europe fairly steady - the Stoxx 50 of leading European shares was trading 0.1 percent lower while the euro was down 0.1 percent at $1.3336. Markets may be worried that the failure of the EU to get unanimous support for more stringent budgetary rules may rattle the foundations of a union created to foster peace and prosperity across Europe following World War II. Even after Friday's long-awaited deal, watched by governments and markets worldwide, the European leaders have huge hurdles still ahead. They are meeting again later Friday to work out what exactly their new treaty will contain and how violators of its strict budget rules will be policed. They want it written by March. Britain, which doesn't use the euro, led the push against a revised treaty tying all 27 EU countries to tighter fiscal union. The others that didn't sign on were Hungary, the Czech Republic and Sweden. Britain's leaders argued that the revised treaty would threaten its national sovereignty and London's esteemed financial services industry. Most EU countries had pushed for an EU-wide accord to avoid a split, but Germany and France, the eurozone's biggest economies, quickly made clear that a deal among the 17 euro countries and whoever else wanted to join was better than nothing.
