The firm says that Chevrolet is pursuing a more independent path that includes a brand-specific fleet sales approach, including the recent appointment of its own fleet boss Keith Jones.

Meanwhile Saab is likely to operate independently following its sale to Spyker. However, the Vauxhall Fleet Team will continue to handle all fleet activities and enquiries relating to Saab as it transitions to new ownership, while GMUK will continue to stand behind its obligations with regard to Saab servicing and warranty issues in the UK market.

Vauxhall Fleet sales director, Maurice Howkins said: 'Clearly, these are exciting times for Vauxhall.

'The British-built all-new Astra has had a spectacular start and continues to go from strength to strength. Add the unrivalled back-up and commitment of Vauxhall's comprehensive dealer network and we have a continuing recipe for future success.'
