The 17 members of the eurozone are vowing to strike their own accord after a bid to change the broader European Union treaty failed. Leaders of the 27-member E.U. have gathered in Brussels in a bid to tackle the sovereign debt crisis threatening the eurozone. A proposal pushed by France and Germany to alter the E.U. treaty to include tighter fiscal controls failed after Britain refused to sign on. France and Germany now say they will push for separate changes within the 17 eurozone states.
