I thank the hon. Gentleman for making that point. What we are talking about is the principle of the matter rather than specific defections from any one party to another. This constitutional question has also been considered by Parliament previously. In 2011, a private Member’s Bill proposed that MPs who changed their party affiliation would have to face a by-election, and in 2020, another Bill proposed extending the Recall of MPs Act 2015 so that a voluntary change of party could trigger a recall petition. Neither progressed through Parliament, but the fact that the issue has arisen more than once suggests that it raises enduring questions about representation and accountability. I would like to share some perspectives from other countries, because this is not a uniquely British debate, and other democracies have taken different approaches. Some, such as India, have adopted strict anti-defection laws under which MPs can lose their seat if they leave the party on whose ticket they were elected. Indian MPs are also, for the most part, compelled to vote with the Whip, which must make votes very, very boring. Others, such as New Zealand, have legislation designed to discourage what is sometimes referred to as “waka jumping”—I am reliably informed that that is effectively jumping from one canoe to another, which I can say from personal experience sounds like a very bad idea—although that approach has also prompted debate about the balance of power between MPs and party leadership. South Africa experimented with allowing MPs to cross the Floor, but later decided that that was a poor idea and prohibited it. That shows that views can change about how best to preserve electoral legitimacy. The UK system has its own traditions and constitutional principles. Party affiliation plays an important role in how Governments are formed and how legislation passes, but MPs are also expected to exercise independent judgment. All of that means that there is no simple or obvious answer to the question raised by the petition of whether the current arrangements already strike the right balance between representation, independence and accountability, or whether there might be merit in exploring alternative mechanisms. What is clear from the petition is that many members of the public care deeply about the relationship between voters and their representatives, how it works in practice and whether they feel that they are being represented in this place. I very much look forward to hearing the views of Members from across the House.
