Can Cameron learn from Wilson?

Few Tories will enjoy looking back on 1974, but they may find it useful to study the second Wilson government and its successor, the Callaghan government, when it comes to the question of Europe.  Back then, we had a government coming to power in the midst of a severe economic climate, and which sought to change the pro-European course that its predecessor had set, including by re-negotiating Britain’s relationship with the EU and by appealing to fraternal parties in France and Britain.
