Concerns raised about effects of coloured immigration in communities in his constituency played a part in his commentary. In March 1968, the month before the "Rivers of Blood" speech, he made his first public references to them in a speech in Walsall, when he described the concern of an anonymous constituent whose daughter was the only white child in her primary school class and suffered bullying from non-white pupils. When Wolverhampton "Express and Star" journalists failed to find the child or the class, the paper's editor and a then personal friend, Clement Jones, challenged him, stating Jones himself had similar anonymous complaints that were traced to members of the National Front (NF). Powell would not accept the explanation and told Jones he had received "bags of supporting mail" as a result of the Walsall speech.
