In 1968, Enoch Powell delivered his "Rivers of Blood" speech in which he strongly criticised Commonwealth immigration to the United Kingdom and the then-proposed Race Relations Bill. When Heath telephoned 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". She believed that his main points about Commonwealth immigration were correct and that the selected quotations from his speech had been taken out of context. In a 1991 interview for "Today", Thatcher stated that she thought Powell had "made a valid argument, if in sometimes regrettable terms".
