National Security and Russia

The hon. Gentleman is making a very powerful speech with which I fully agree. When we were putting sanctions on Russia after it annexed Crimea, I was privy to information on discussions with the European Commission about how the octopus arms of the Russian state were all over the energy sector across the European Union and how it was using devious means to get its way. May I therefore invite him to take on the logic of his speech that we use not just military but diplomatic means, so that we can use energy policy to take the money away that is fuelling Mr Putin’s military and intelligence?
