Sales of new cars in Britain slumped for an eighth straight month in November, largely on demand for diesel cars plunging further, industry data showed on Tuesday.

New registrations for vehicles overall slid last month by 11.2 percent year-on-year to 163,541 vehicles, with demand for diesel-powered cars sliding on UK government plans to improve air quality, the Society of Motor Manufacturers and Traders said in a statement.  

The SMMT has meanwhile blamed falling demand also on uncertainty surrounding Britain's Brexit deal with Brussels.

"An eighth month of decline in the new car market is a major concern, with falling business and consumer confidence exacerbated by ongoing anti-diesel messages from government," said SMMT chief executive Mike Hawes.
