Thank you, Sir Roger, for calling me to speak in this important debate. I have to declare an interest because—[Hon. Members: “You’re 16.”] It is a somewhat different interest to the one that hon. Members are suggesting. My wife is not 16, or 17, but she is French. The hon. Member for Edinburgh East (Tommy Sheppard) talked about divided households. I can say that none is as united as mine on this issue. My wife has identified what hon. Members would be well advised to note. As a constitutional expert in French law, she realises that what we are talking about is not a tactical political change, but a major constitutional change to the state of the United Kingdom.
I understand that nations within our great kingdom have taken different decisions, and I recognise and respect the right of those decisions to affect the laws and conduct—
