The petrol blockade may have produced a £60m windfall for motor insurers, an insurance expert claims.

Motor claims, running at 75,000 a week according to the ABI, were expected to fall dramatically as petrol became scarce.

Nigel Munns, actuarial consultant at Bacon & Woodrow, calculated that the insurance industry would save 1% on its annual £6bn claims bill for each week that the blockade reduced car mileage.

The saving to insurers could be £60m.
