Who knows, but the EU need the UK more than the other way round. I think the trade 'deficit' is something like £50 billion a year, so the queues of lorries will be longer in France and Belgium. Plus you can add the £40 billion we won't pay the EU. The UK economy is stronger than all EU countries bar Germany - they'll be sh*tting themselves with a 'no deal' brexit, which, I guess is May's strategy to get some last minute concessions..
