Member Defections: Automatic By-elections

Contribution

I am loath to say that I am delighted to have you in the Chair, Sir Roger, because I feel we are all missing out on a good hour’s worth of content with you there rather than here, but it really is a pleasure to serve under you. Since the 2024 general election, we have seen the start of a slow procession of former Conservative Ministers and Members of Parliament moving to Reform UK. These are people who spent years in government and claimed they were there to make a difference—and they did leave a difference behind them, but that difference was far too many crumbling public services, a cost of living crisis and a legacy of broken promises. Rather than accepting responsibility for their actions, they have crossed the Floor for a new start, making no attempt to rebuild the public trust they broke. My hon. Friend the Member for South Cotswolds (Dr Savage) alluded to a pattern of very large concentrations of signatures making their way on to this petition—one of politicians prioritising their own political future over the parties their constituents voted for. I understand why some voters feel betrayed and that their MPs are not moving to another party from a principled stance. These MPs clearly feel they are fleeing a sinking ship and are hoping that voters are too distracted to notice. But their constituents have noticed, with almost 130,000 people signing the petition that has resulted in this debate, including more than 200 in my Hazel Grove constituency. I understand people’s frustrations, especially as many of the constituencies that had the highest numbers of signatures were those whose MPs had defected. They feel, rightly, that something has been taken from them. For that reason, some feel betrayed. Most voters will not have read the full manifestos of all the candidates standing for election, but I can see why people would be unhappy, particularly when their MP joins a party that does not align with their views and values or whom they thought they had voted for. We are talking about a party whose former Welsh leader was imprisoned for a bribery conviction related to Russian connections, a party filled with swivel-eyed Trump supporters, a party that platformed a vaccine conspiracy theorist at its most recent party conference—it is hardly surprising that people do not feel their values are reflected in Reform UK. However, our electoral system means that people vote for an individual to represent their area, not directly for a party. Our system is not set up automatically to call a by-election whenever an MP defects or is removed from a political party, or indeed when a party of government moves firmly away from a manifesto commitment. Nevertheless, the disillusionment that voters are experiencing points to something larger—a fundamental problem with how our democratic system currently works. The Liberal Democrats believe that our political system needs fundamental change to restore the trust that voters have lost. First, we need to change the way we elect our MPs.
