§ Mr. Marlowasked the Secretary of State for Employment, in calculating the retail price index, how he estimates the degree to which business men will pass on any increase in the price of derv.
§ Mr. Jim LesterThe retail price index is based on the prices households actually pay for the goods and services they buy. The prices are obtained directly from retail outlets and other sources throughout the country. They reflect the degree to which businesses have passed on any increases in the price of derv, and no estimation is therefore necessary.
