„Make no mistake, the real power resides not where present authority is exercised but where it is expected that authority will in future be exercised. The magnetic attraction of power is exercised by the prospect long before the reality is achieved; and the trek towards the rising sun, which is already in progress in 1972, would swell to an exodus before long. What do you imagine is the reason why Roy Jenkins is prepared to resign the front bench and divide his party in the endeavour to give a Conservative Prime Minister a majority in the House of Commons? The motive is not ignoble or discreditable— I am not asserting that— but it is a motive which it behoves people in Britain well to understand. It is the ambition to exercise his talents on the stage of Europe and to participate in taking decisions not for Britain here at home but for Europe in Brussels, Paris, Luxembourg or wherever else the imperial pavilions may be pitched. He does not, I assure you, forsee his future triumphs and achievements where his predecessors have seen them in the past – at the despatch box in the House of Commons or in the Cabinet room at Downing St. These are not good enough: the vision splendid beckons elsewhere.“
— Enoch Powell
Speech at Millom, Cumberland (29 April 1972), from A Nation or No Nation? Six Years in British Politics (Elliot Right Way Books, 1977), p. 42. Jenkins had resigned from the Shadow Cabinet and as deputy leader of the Labour Party due to Labour's opposition to British entry into the EEC. Jenkins wrote to Powell to claim what he said was "totally untrue". Four years later Jenkins would leave front line British politics to become President of the European Commission.
