HC Deb 22 March 1984 vol 56 cc529-30W
Mr. Eldon Griffiths

asked the Chancellor of the Exchequer in view of his decision to abolish the halfpenny, why he announced increases in duty on petrol and on derv in halfpenny numbers rather than whole pence.

Mr. Hayhoe

My right hon. Friend followed trade practice, which in the case of petrol and derv is to show prices at the pumps in amounts calculated to one tenth of a penny per gallon or litre.
