SIR - David Marshall is not the first to suggest the abolition of vehicle licence duty in favour of adding a few pence to the price of petrol, ensuring the Chancellor of the Exchequer gets his revenue (T&A, September 9).

Unfortunately there are a few ramifications to consider, not least the inevitable increase in the cost of goods in our shops, especially those dealing with food as hauliers would have to charge more for deliveries. Ultimately this would defeat the Chancellor's pledge to keep down inflation.

On top of that, most assuredly there would also be an increase in rogue drivers filling up their tanks and driving off without paying.

I'm afraid Mr Marshall's cunning plan', like all those of Baldrick, is a non-starter.
