How to explain his seemingly contradictory characteristics? Pimlott solves some of the mysteries; the book is detailed until Wilson's final phase as prime minister in 1974.Churchill by Roy Jenkins (2001)Jenkins writes as a politician as well as a historian, analyzing Churchill's historic moves from the opinions of one who had also spoken in the Commons.Jenkins had resigned from high positions in battles over policy, and as one that changed parties, though not as frequently as Churchill did.Roy Jenkins by John Campbell (2014)Campbell calmly narrates many political and personal dramas, including Jenkins'intense relationship with Anthony Crosland when they were both students at Oxford.Campbell also addressesJenkins'various affairs with women.Like Jenkins'political heroes, he led many lives.Campbell is sharp in describing each of them.Diaries, V olumes One to Six by Alastair Campbell(2017)Love or hate him, Campbell remains the master of the inside story, not just because of his unusual ideas on the relationship between Tony Blair and Gordon Brown.This is an incredibly detailed book on what it's like to live inside No.10: the cruel space of events; and the constant conflict with the media.语篇解读：本文是一篇应用文，主要介绍了五本有关改变历史的世界伟人的传记，书的作者是掌握这一伟人的第一手资料者。
