Well, I have not put this well.
Members don't take maternity leave in any formal way, so it's very difficult for me to say. You would have to ask each individual member, I think, how long they think they were on maternity leave, because it's a private arrangement, in essence, between them and their party whips.
Some of them are paired during absence. In other words, they're not expected to come to Westminster to vote, and someone from the other party—if you know pairing—and possibly a different person each day, is paired with them to cover their absence.
Somebody will have an idea as to how long. I saw a member who had very recently had a child. She was sitting in the atrium here in Portcullis House, and naturally I went up to see the child. I said, “What are you doing here? I thought you were away”, and she said, “It's a keeping-in-touch day, a KIT”, which of course we have in our ordinary maternity regime for staff.
It's quite difficult—I'm sure it's different in Canada—to keep politicians away from Westminster.
