Of course. It has never been the view of my party that, if other member states wish to proceed with the single currency in accordance with the criteria set out in the Maastricht treaty, they should not do so. Of course they are perfectly entitled to do so. All that we would have insisted on would have been a firm application of the Maastricht criteria. They were set out in that treaty and they should have been observed. The Prime Minister said that he would ensure that they were observed, yet he did not. That is not likely to be conducive to the success of the single currency.
