98.784 per cent of British MP's set to break their Election promise

Here’s a paradox, 650 out of 658 MPs fought the last election on the promise of a referendum on the European constitution. The above quote is the opening of an article "Save us from the Diplomats' by MEPs Dan Hannan and Douglas Carswell in the Daily Telegraph's "Think local" series, linked here. Have Britain's elected MPS really sunk so low that they are prepared to let Blair, Brown and the entire EU establishment and other European leaders get away with their constitution deception? If so, not one sitting MP should ever be elected ever again!
