Around 8,000 people packed into the home of Lotus at Hethel, near Wymondham, as the legendary carmaker marked seven decades of producing race and road cars.

It came as the firm's parent company, Geely, revealed plans for a multi-million pound investment in the site.

Marcus Blake, Lotus's commercial director, said: 'We're delighted. The weather's come out to play and so have 8,000 owners, fans and employees, who have come to celebrate an iconic brand.'

He added the engineering brilliance of the firm's founder, Colin Chapman, was in the DNA of every car Lotus had produced since production began.
