Mr Byers had lied to the Commons and should resign immediately

Amid the ‘tributes’ showered on the late Sir Edward Heath earlier this week, there was, inevitably for a man who upset so many people, the occasional reference to his most catastrophic service to his country: his decision to take us into what is now called the European Union. It was said, fairly, that Heath was not straight with the British people about this. The 1970 Conservative manifesto promised to negotiate about our possible entry; but entry took place without any further reference to the people. In a similarly secret way he effectively abolished our fishing industry and made a commitment — happily unfulfilled — to take us into a single European currency. Yet, as was said in many of the obituaries, Heath was a man of integrity. He had a set of principles and always lived by them — and spoke up for them when they were under attack. For all his high-handedness, it is hard to prove Heath ever actually lied in his public life.
