A reflection on the state of democracy and observance of the British constitution in the United Kingdom.In The Bonfire of the Decencies, Peter Hennessy and Andrew Blick use Boris Johnson s tenure as prime minister to argue that mechanisms for the upholding of constitutional principles in the United Kingdom are deficient and require an overhaul. They show that, from the outset, Johnson s time in office was a source of serious disruption that saw standards and integrity compromised, as well as constitutional values violated. Those problems, however, did not end with Johnson s removal from office. Rather, they are part of longer-term tendencies in the UK, and of a worrying international trend towards the weakening of democracy. Hennessy and Blick analyze the pre-existing vulnerabilities that Johnson exposed in the UK system of government and conclude with a series of proposals to repair the damage and prevent a repetition of this anxious episode in the UK s political history.
