Which British Prime Minister sacked Enoch Powell after he made his controversial "Rivers of Blood" speech?

Sir Edward Richard George "Ted" Heath (9 July 1916 – 17 July 2005) was a British politician who served as Prime Minister of the United Kingdom from 1970 to 1974 and Leader of the Conservative Party from 1965 to 1975.

In April 1968, Enoch Powell made his controversial "Rivers of Blood" speech, which criticised immigration to the United Kingdom. Soon afterwards, Heath telephoned Margaret Thatcher to inform her that he was going to sack Powell from the Shadow cabinet; she recalled that she "really thought that it was better to let things cool down for the present rather than heighten the crisis". The next day, Heath sacked Powell. Several Conservatives on the right protested against Powell's sacking. According to Heath, he never spoke to Powell again.

John Enoch Powell (16 June 1912 – 8 February 1998) was a British politician, classical scholar, author, linguist, soldier, philologist, and poet. He served as a Conservative Member of Parliament (1950–1974), then Ulster Unionist Party (UUP) MP (1974–1987), and was Minister of Health (1960–1963).
