Carmakers accused of 'clutching at straws' over retrofitting polluting diesels

VW, BMW, Opel and Daimler's promise to fix 5 million cars not enough to undo the damage done by emissions scandal, say campaigners

Major car makers are being accused of clutching at straws after they agreed to fit software to 5m diesel vehicles in Germany to reduce harmful emissions by up to 30%.

VW, Daimler, BMW and Opel made the decision at a summit with leading politicians in Berlin. They have been under pressure since the diesel emissions scandal two years ago exposed how VW and - it is suspected - other manufacturers have been cheating the testing regime.
