I’m not going to get in to the politics of Brexit – far too busy for that. Like it or not though this is history in the making and it’s very likely to have an impact on your small business. I thought it would be interesting to put together a consolidated timeline of events. An impartial version of the story of Brexit… so far.


This is a completely non-political, totally on-the-fence web site. For posterity reasons I thought it would be interesting to keep track of what’s been going on. So here’s a list of everything EU-related that’s happened since World War 2. Key moments of history shown in red:
