Diefenbaker was a great orator. He was best in opposition where his indignant speeches kept the government of the day on it's toes. Debates between him and Jack Pickersgill went on daily, with no prisoners taken. When he formed the government the table was turned and Pickersgill was a real thorn in his shoe. Tommy Douglas could shut them both up though by using wit, a milder manner, and common sense.
