Madam Deputy Speaker, I would like to begin by saying how much I admired the way in which you so sensitively and generously responded to my hon. Friend the Member for Mitcham and Morden (Siobhain McDonagh) when she spoke about her campaign on glioblastoma in memory of her sister. You really did speak for the whole House, and it was greatly appreciated.
The pleasure of participating in such a debate is in the range of topics covered, and I agree with many of the subjects that have been chosen. The hon. Member for Chatham and Aylesford (Tracey Crouch) spoke very well about the badger cull and the importance of science, and my hon. Friend the Member for Rochdale (Tony Lloyd) spoke very well about the importance of science in deep-sea mining.
Sometimes we need to fact-check our speeches, and I took the opportunity to fact-check the complaint made by the hon. Member for Harrow East (Bob Blackman) about the Mayor of London giving himself an exemption on his car. I am reliably informed by the Mayor’s office that this is not the case, and that the Mayor’s own car does not have an exemption. As we think of Sir David, who was such a part of this particular debate, we need to temper our criticisms so that people who are as high in public life as the Mayor are not unduly targeted.
