Parliamentary Voting System and Constituencies Bill

My Lords, this is one of the most important issues before us on Report on Part 1 of the Bill. The amendment tabled by my noble friend Lord Rooker is eminently sensible. Surely we should all be able to agree that, where major constitutional change is concerned, there should be a search for consensus. Major constitutional change should not be made on a small participation in the vote. I fear that turnout at the referendum will be low, partly because the question of whether we should switch from first past the post to the alternative vote system of elections is fairly obscure and technical, and partly—this is a very important factor—because this legislation, proposing as it does such important changes to our constitution, has not, as convention and normal practice require, been the subject of public consultation by way of a Green Paper or pre-legislative scrutiny. That means that there has not been an extensive debate, other than in your Lordships’ House, where the extent of the debate has been well justified in these extraordinary circumstances. In the time that will be available between this Bill reaching the statute book and the day that the Government have appointed for the referendum, 5 May, there will be very little possibility of the Electoral Commission explaining to, informing and, indeed, educating the people of this country about the choice that it will fall to them to make. Those are significant reasons why we should insist that there should be a substantial turnout if the result of this referendum is to be binding, and I think that a minimum turnout of 40 per cent, as proposed by my noble friend Lord Rooker, is well judged. I think that there should always be a high hurdle in a referendum. It would be intensely undesirable if Governments got it into their heads that referendums were a readily available, convenient way of introducing a change that they happened to think was desirable. I very much heed the advice of the Constitution Select Committee of your Lordships’ House. In its report on referendums, it has made it very clear that it considers referendums to be in principle undesirable and inconsistent with the principle of parliamentary government. Although the committee concedes that referendums may be appropriate on significant constitutional issues, I am sure that the tenor of its recommendations is that we should not automatically reach for referendums as a convenient device for the Government of the day; rather, it should be rare and difficult for a proposition to be put to a referendum. I take the view that, where there is to be a referendum, it should be advisory rather than mandatory. Again, my noble friend Lord Rooker has proposed to the House a very sensible compromise: if there is a majority on a genuinely substantial turnout, we accept that this referendum will be mandatory but, if the turnout is less than 40 per cent, the question of where we go from there will come back to Ministers and to Parliament. That all seems very sensible. Surely, when we are developing constitutional change, we should do all we can not only to achieve consensus between the parties in Parliament but to achieve a substantial consensus in the country. Therefore, I support the amendment.
