Things have changed over time, and I dread to think how many by-elections we might have had in recent years had we needed one every time someone was appointed to the Cabinet. I suspect that would have cost the public purse something quite significant. In the period of which the hon. Member speaks, there was a slower churn of those in the Cabinet, and there was not quite the political turmoil that we have seen in recent years, which would make such a situation challenging. It is a fair point, though, because the change of circumstance in that situation is far less than the change of circumstance of moving from one party to another. As I have said, it is not the principle of the issue that concerns me, but the practicality. If Parliament did introduce legislation, it would have to be absolutely spot on and watertight, to ensure that it did not degrade the link between individual Members of Parliament and their constituencies, and that the party system did not become more empowered through any such change. That is my principal concern. Our constitution and political system have drawn their strength from the respect we have for tried and tested convention, and we must always be wary of the danger of rushed constitutional change and unintended consequences. We need only to look at the recent past to see how previous attempts to enforce rigidity within our system have failed. Most notably, the Fixed-term Parliaments Act, which was seen as an important tool during the coalition Government, ultimately was viewed to have failed and was rightly repealed during the last Parliament. The independence of Parliament and of an individually elected representative to do what they believe is in the best interests of their constituents is one of the longest-standing conventions in our political system. While I sympathise with the frustrations of the petitioners and understand their desire to see the proposed change enacted, I believe we would be unwise to surrender that independence.
