"I have since come to know Michael Heseltine well, and now count him as a friend. But at this time I found him hard to read. He made no effort to enlist me as an ally even though I knew that we had several points in common. We both held a generous view of the role of the Conservative Party in social matters; neither of us denied the importance of government action in carrying this through. We both believed strongly in Britain's role in the European Union, though Michael carried his enthusiasm for integration faster and further than I did. But our temperaments were different. Michael was a cavalry leader, relying on the excitement of a charge to carry him to success. For example, I was surprised and dismayed by his vehement desire to transform the structures of the Civil Service which had always been part of my working life. Michael relished and I disliked the scent of danger."
