BMW is recalling all new Minis because of a fault that could cause a fire when the cars are being filled with fuel.

The problem was discovered when testers found special paint used to earth the fuel filler neck was wearing off too quickly. A build up of static electricity could cause a spark when the pump nozzle is inserted which could ignite fuel vapour.

500 models already delivered to customers will be recalled for modification work.

BMW says there had been no explosions and that the risk was small. However, the company said it was aware of two cases where a build-up of static electricity had caused a fire.

BMW hopes to sell 100,000 Minis worldwide during the coming year.
