It's 300 years since Sir Robert Walpole took office as the first recognisable office holder of Prime Minister. To mark the anniversary, the historian and biographer Sir Anthony Seldon, examines how the role came about and why it has survived despite various crises and periods of change in the life of the nation. What do Walpole and Boris Johnson, the 55th occupant of the office, have in common?

Former Prime Ministers, Foreign Secretaries, Cabinet Secretaries and others at the heart of government talk about the pressures on the modern office and the responsibilities that come with it. Has the job become too difficult to perform effectively and what could be done to enhance the role of Prime Minister?

The second programme explores how the office survived from the Victorian era to the present day and how it was shaped by a small number of exceptional office-holders.
