UK car sales set for first annual decline since 2011 after September slump

British new car registrations on Thursday appeared on course for their first annual fall since 2011 after a 9.3% tumble in September, a month which normally accounts for around 15% of demand. Sales were hurt by business and political uncertainty as Britain prepares to leave the EU and confusion over government plans on diesel and petrol cars, which could include new levies or restrictions, the Society of Motor Manufacturers and Traders (SMMT) said.
