I support the amendment moved by my hon. Friend the Member for Wood Green (Mrs. Butler). We have had many figures and alleged facts from the hon. Member for Bedford (Mr. Skeet). It is interesting to note that over a period of years the number of countries taking measures such as is suggested tonight has substantially increased. The Russians first introduced a ban upon lead in petroleum in the 1950s. Lest this is thought to be a Communist quirk, let me say that the EEC countries almost without exception, and now America, are proposing to introduce similar legislation.
