European Commission (EC) president, Jean-Claude Juncker, has conceded the Brussels bureaucracy has made "major mistakes" in the past. His comments, in Russia, came a week before the UK is due to vote in its highly contentious referendum on whether it stays or exits the EU. Most carmakers operating in the UK want the country to remain 'in' but the opposite view is held by other auto industry-related firms such as construction equipment maker JCB.
