Contributor(s): Robin Harris | Drawing on his new book, The Conservatives-A History, Robin Harris will review the different styles, strengths and weaknesses of successive Conservative leaders, and analyse the problems which they and the Party faced at different junctures. He will consider whether there are lessons to be drawn from this historical experience for the present and future. Robin Harris began to work for the Conservative Party in 1978, becoming Director of the Conservative Research Department, a government political adviser and a member of Prime Minister Margaret Thatcher’s Policy Unit. When Mrs Thatcher left Downing Street, so did he, going on to assist her with books and speeches. In recent years, he has written an authoritative history of the city state of Dubrovnik and an acclaimed biography of the French statesman, Talleyrand. He is currently working on a biography of Margaret Thatcher.
