I am most grateful to the hon. Gentleman for giving way. I came into the Chamber in 2015 fully intending to vote for a change in the law. However, as I listened to the debate, although I was completely persuaded by the points that he is now making, I was unpersuaded that that was the right law or that the right people had been persuaded that it was the right law. What has changed between then and now that he thinks would bring the House to a different conclusion?
