Our economic troubles have been going on for almost half a decade, with no end in sight. They are the worst crisis to hit Britain since the Second World War. Then we suspended party politics and created a government of national unity. Is it too much to ask that our politicians might do the same today? Is it too much to ask that they should practise what they preach, allow themselves to be suffused with the Olympic spirit, and come together to pull the nation out of its slough of economic despond?
