It has almost been 300 years since Sir Robert Walpole arguably became the first holder of the office of Prime Minister in 1721 - an office which today is under scrutiny like never before. The Prime Ministers series of 55 podcasts brings to life all 55 of Britain's 'First Among Equals' through interviews with the authors of all 55 essays in Iain Dale’s new book The Prime Ministers: Three Hundred Years of History. From the obscure 18th-century figures like the Earl of Shelburne and Henry Pelham to 20th-century titans like Churchill and Thatcher, these podcasts provide a much-needed reminder about their motivations, failures and achievements.
