On a point of order, Mr Speaker. I seek your guidance about the convention that Members should notify each other when they visit their constituencies. On the way to my surgery on Saturday morning, I came out of Hillhead subway station and met a bunch of very drookit-looking Labour supporters, and when I asked them whether they were waiting for someone special, they said no. However, at the end of my surgery, I read on social media that Jeremy Corbyn, the leader of Her Majesty’s loyal Opposition, had in fact visited that street and undertaken a walkabout. I had received absolutely no notification of that. I understand that an email was sent to my hon. Friend Alison Thewliss, but he was not in Glasgow Central.
