Once we have confirmation of Russia’s involvement in the Salisbury incident, I think we should withdraw from the World Cup. I can think of no other way of bringing this to the world’s attention, and convincing Putin we are treating this seriously, unlike the last occasion. I think this is the only action which would properly affect Putin as he attempts to portray Russia as a leading influencer in world affairs. I know that all ‘keep sport out of politics’ believers will disagree, but I really can’t see a more appropriate course of action in preventing state terrorism.
