Member Defections: Automatic By-elections

Contribution

It is a pleasure to serve under your chairmanship, Sir Roger, and to take part in this debate on automatic by-elections following Member defections. I thank everybody across the country who has signed the petition. I have brought with me a list of every MP who has ever defected. Given the lack of a time constraint, we could go through it, but I would prefer to concentrate on the arguments. I congratulate the hon. Member for South Cotswolds (Dr Savage) on introducing this important debate. My hon. Friend the Member for Keighley and Ilkley (Robbie Moore) made an excellent contribution with some very powerful arguments indeed, made all the more persuasive by the fact that he is a much-loved local Member of Parliament. He has as much personal support as party support, and has defied political gravity in recent times. I absolutely sympathise with and understand a lot of the arguments he makes. I will outline an alternative viewpoint that relates not necessarily to principle, but to practicality and the challenges that may arise if a change of law were brought in to deal with the ongoing issue of Members choosing to change from one party to another. I fully sympathise with the frustration that many voters feel when their Member of Parliament chooses to defect to another party. At a time when our country faces many pressing challenges, it is easy to understand why many people feel as though their representatives, if they defect, are choosing party politics over real-life concerns. I would not deny the reality that many voters choose their candidate in an election with party labels in mind. We should not be arrogant enough to assume that everyone voted for us as individuals, regardless of our party alignment. Despite my hon. Friend’s popularity, it is absolutely party alignments, labels and manifestoes that persuade people at general elections. We can do our best to be great servants to those we seek to represent, but much of the time that decision is made on a wider, more national position. Like most Members, I am proud to work alongside like-minded individuals who share my core beliefs about how we can change our country for the better. Political parties have been an established part of our system for more than three centuries, and they have an irreplicable role in ensuring that the business of government and opposition can work effectively. John Grobham Howe is said to be the first MP to have defected when, in 1698, he switched allegiance from the Whigs to the Tories, so the discussion today is certainly not about a new phenomenon. It is ultimately only Members themselves who can know their motivations for choosing to leave their existing party. I know that many Members would consider it entirely dishonourable to do so without seeking a mandate from their constituents, and I fully understand why many think that allowing a by-election to take place after defecting is very much the right thing to do. However, making that an automatic requirement could have unintended consequences that would only undermine Members’ standing as elected representatives of the people. We who serve in this House do so as representatives of our constituents above all else, regardless of which party we represent. We are elected to do what we think is in the best interests of our constituents, above all other considerations. If a Member chooses to defect, that should be because they have judged, rightly or wrongly, that doing so is in the best interests of their constituents. Their constituents are, of course, free to disagree with that judgment, and may well choose to elect a representative of a different party at a later election. However, if we wish to uphold the principles that have made our political system one of the most enduring in the world, Members must be deemed fit to serve as representatives on the basis of their record of serving their constituents’ interests, and not simply on the basis of their party label.
