I thank my hon. Friend very much for giving way. He is clearly passionate and knows a lot about the subject. However, one shadow hangs over all this: the murder of Alexander Litvinenko. Speaking as an observer who comes to Anglo-Russian relations from a different angle—or from an angle that is not too used to them—that was a crime carried out on British soil, seemingly with the connivance of the Russian state, so until it is dealt with, our relationship will always be poisoned to a certain extent.
