These are highly technical matters. My hon. Friend has a record of getting his head round such matters, and we have had excellent briefing from the RMT and support from the petitioners in this. I am not
surprised that other Members are not on top of the matter. In all fairness to those who could not be present today, such as my right hon. Friend the Member for Tooting (Sadiq Khan), we should not pick on individual Members. However, I am glad to hear that my hon. Friend is holding back on his endorsement of a mayoral candidate—I am sure that all the candidates are waiting for it with bated breath.
