If we had some more of that detail, we would be a little more reassured, and we would not be able to attribute anything other than good intentions to the Government in this process. However, that is not the situation we are in at the moment. Words are extremely important in this process, because words and meaning have to be shared for us to move forward. If we look at what happened last Friday, we can see a clear example of how one set of words can mean two entirely different things to two different people. It looked as if the Prime Minister-I am sure she genuinely believed this-was signing an agreement on behalf of this country with the 27 other member states of the European Union. She described it as a series of commitments that were being made by this country at this interim stage in the process. Within 24 hours, however, we had the spectacle of one of her closest advisers turning round and taking to the public airwaves to say that these were not commitments at all, but merely a statement of intent. He was sternly reprimanded and corrected the following day, but that does show that, unless we are very careful and precise about the words we use, there is scope for ambiguity and, therefore, misunderstanding. The first word we should be very careful about is “deficiencyâ€, which appears throughout the Bill, and which is the subject of several of the amendments I am talking to. The word “deficiencyâ€, as it appears in the Bill, need not necessarily mean the absence of something; the EU retained law being brought over could also be deficient if it contains something that prevents the Government of the day from doing what they want to do. I do not want to engage in hyperbole or to give dramatic, unreasonable examples, and I am sure that, for the vast bulk of things, we would all expect to have primary legislation to make policy change, but this issue does open up the scope for making significant policy changes without reference to this Parliament or to primary legislation. We have already had mention of the working time directive-the 48-hour limit on weekly work. I am not suggesting that the Government would necessarily want to use these powers to overturn completely that and to substitute 48 with 72. However, a Minister in the future-in the period of transition-might well find that the 48 hours is overly prescriptive in a mandatory sense, and might choose to make it more of an advisory notion, rather than something that is absolute and that can be challenged. With the stroke of a pen-overnight-the rights at work of millions of people in this country could simply be eroded. If the Minister is saying that that is not the intention and that it will never happen, he should support amendment 75 in the Lobby tonight, which will make sure that will not happen, because it will exempt workers' rights from the scope of the legislation.
