HC Deb 05 December 1939 vol 355 c479W
Mr. Glenvil Hall

asked the Chancellor of the Duchy of Lancaster whether he is aware that most brands of margarine sold in Great Britain are inferior to butter in vitamin qualities; and whether he will take steps to prohibit the sale of any margarine which is so inferior?

Mr. Lennox-Boyd

A large proportion of the margarine entering domestic consumption is already vitaminised. Consumers thus have the opportunity of exercising their own choice in this matter, and I see no necessity to prohibit the sale of margarine the vitamin content of which is inferior to that of butter.
