The biggest argument Powell and Heath had during Powell's time in the Shadow Cabinet was over a dispute over the role of Black Rod, who would go to the Commons to summon them to the Lords to hear the Royal Assent of Bills. In November 1967, Black Rod arrived during a debate on the EEC and was met with cries of "Shame" to Op it". At the next Shadow Cabinet meeting Heath said this "nonsense" must be stopped. Powell suggested that Heath did not mean it should be ended. He asked whether Heath realised that the words Black Rod used went back to the 1307 Parliament of Carlisle and were ancient even then. Heath reacted furiously, saying that the British people "were tired of this nonsense and ceremonial and mummery. He would not stand for the perpetuation of this ridiculous business etc".
