London Motor Show organisers Clarion Events will soon announce changes to the autumn event in an attempt to win back carmakers which have announced they do not want stand space.

A spokesman said: “We believe some manufacturers are reconsidering their decision not to be at Earl's Court.” Clarion executives have made a presentation to Ford of Britain marketing director John Mendel in the hope that the UK market leader will not pull out.

In December, Ford of Britain chairman Ian McAllister told Automotive Management a decision had not been reached. Ford might not attend because the absence of many manufacturers would reduce the appeal, or it might see an opportunity.

Daewoo is the latest to join a stream of companies abandoning the show. Others include BMW, Mercedes-Benz, Peugeot, VW, Audi, Seat and Skoda.
