 Although Osborne's views on immigration were generally regarded as somewhat extreme by the Conservative Party leadership, in March 1965 the party's MPs supported his Bill that sought to introduce 'periodic and precise limits on immigration'.Although the Bill failed at its first hurdle, the fact that it received the support of the Conservative Party leadership reflected the party's gradually hardening position on immigration into Britain from the 'New Commonwealth'.Later in 1965, he called on the Labour government of Harold Wilson to "ban all immigration except for genuine students and professional people who will return to their native countries at the end of a limited stay".
