Dr Julian Lewis: I am sorry to interrupt the right hon. Gentleman's [Tom Clarke's] flow, but I cannot resist interjecting at this point to confirm one contrast between the US and British film industries: the US film industry is willing to take far greater poetic licence. I have in mind the new US film about the alleged capture of a German submarine by Americans who, supposedly took hold of the Enigma machine, thus shortening the war by enabling the code-breakers to do their work. I wonder whether, even at this late stage, representations might be made to the American producers to allow a walk-on part to my constituent, the then Royal Navy Sub-Lieutenant David Balme DSC, who actually captured the Enigma machine from the U-110 seven months before America even entered the war?
