Racism is alleged to have existed in the Conservative Party since at least 1964. Conservative shadow defence minister Enoch Powell's "Rivers of Blood" speech in 1968 was both influential and widely regarded as anti-immigrant with racist overtones; the party's leader at the time, Edward Heath, condemned it, although some Conservative MPs defended Powell's speech. Since then, accusations have been made about several leading members of the party and its policies; these have related to prejudice against non-white people.
