The Observer’s political editor has reported on Britain’s place in the EU for more than 30 years. Here he charts the key moments in a stormy relationship and the missed chances to save it from destruction

Last week, with the end of the UK’s 47-year membership of the club of European nations just days away, I looked back at some newspaper cuttings from my time as a Brussels correspondent. A picture of worried-looking farmers eyeing up their cattle at a market in Banbury stared out alongside banner headlines. “British beef banned in Europe. Cattle prices fall. School meals hit. EU ‘rules’ broken.” Among the many crises in British relations with the EU down the years – from Margaret Thatcher’s bust-up over the European budget in the early 1980s to the UK’s exit from the ERM in 1992 – the beef war between London and Brussels ranks among the biggest.

It was 29 March, 1996, and the European commission had just announced a worldwide ban on the export of British beef. The EU’s executive opted for decisive action after the Tory government admitted there could be a link between “mad cow” disease and the mutant strain of Creutzfeldt-Jakob disease which could kill humans. I had been in Brussels less than three months. It was a huge story, and reading through articles I had written at the time, it felt like yesterday. But what was most striking, as my mind fixed again on events of 24 years ago, was how relevant that one prolonged and tortuous episode seemed today, in the context of Brexit.
