Rivers of Blood Speech
On April 20 1968, the British politician Enoch Powell made a controversial speech in Birmingham to the annual meeting of the West Midlands Conservative Political Centre, in which he warned his audience of what he believed would be the consequences of continued immigration from the Commonwealth to Britain. Because of its allusion to Virgil saying that the Tiber would foam with blood, Powell's warning became known as the Rivers of Blood speech.The next day, Prime Minister Edward Heath sacked Powell from his Shadow Cabinet. Powell never held another senior political post.
The speech was followed by strikes, in particular in London's docklands, both in support and in opposition. Powell gained considerable support from the public, receiving over 100,000 letters and was supported by MPs such as Sir Gerald Nabarro. Some supportive commentators attributed the surprise 1970 election victory by Edward Heath on the swing in Powell's West Midlands heartland, while other more hostile commentators have said that this speech alienated many immigrants from the UK Conservative Party.
