asked the Secretary of State for the Environment if he will make a statement on the extent to which unleaded petrol is now available in service stations.

I understand from the United Kingdom Petroleum Industry Association that there are now 211 service stations selling unleaded petrol in the United Kingdom. My right hon. Friend the Chancellor of the Exchequer's provision for a 5p duty differential has removed the remaining price barrier and I expect to see a major expansion of unleaded petrol outlets this year.
