Wolf Hall: The Mirror and the Light (on BBC iPlayer) adapted from the final book in Hilary Mantel’s trilogy, and directed by the BAFTA award winner Peter Kosminsky, traces the final four years of Thomas Cromwell’s life. After the execution of Anne Boleyn, Henry VIII’s fixer and royal secretary, Cromwell, continues his climb to power and wealth, becoming the most feared and influential figure of his time. But as the King becomes more irascible and Cromwell’s enemies circle, it’s only a matter of time before he’s brought down.

George Villiers, Duke of Buckingham was King James I’s favourite and then Charles I’s confidante and first minister. But he too fell spectacularly from grace, amid political and sexual intrigue. In her biography, Scapegoat, Lucy Hughes-Hallett dramatizes the Duke’s transformation from a young man who traded on his beauty to one with immense wealth and political power.

The late novelist Hilary Mantel compared Cromwell with Boris Johnson’s political advisor Dominic Cummings, another outsider whose political influence spread far and wide. The columnist and Associate Editor at the Financial Times, Stephen Bush, considers the role of today’s fixers and ‘special advisors’; how much power they can wield; and as the political cycle turns, whether their downfall is inevitable.
