from John Bowden, chief executive, Wholesale Confectionery and Tobacco Alliance

Sir; The increase in the London Congestion Charge for delivery vehicles to £7, being imposed from July 4, deals a further blow to an already embattled independent sector.
While the Wholesale Confec tionery and Tobacco Alliance appreciates the different purpose of commercial and private road use, it believes a £1 differential does not reflect this.
Although the charge is intended to reduce congestion, shops need supplies and the number of deliveries cannot be reduced.
Therefore the charge on commercial deliveries is a revenue-raising charge and has a disproportionate impact on small shops and their customers.
Congestion should be eased. However, commercial vehicles of 11 tonnes and under should be exempt from the charge as it is detrimental to the vital role they play.
