Members Behaving Badly

A History of Britain in 52 Parliamentary Rogues

Published 19 Feb 2026

Over the centuries, the House of Commons has been full of Members of Parliament of courage and conviction – remarkable people doing remarkable things for the good of all. Yet, just as often, it has harboured cheats and liars who have played games, played the markets and played the people who put trust in them. There have been abusers and kidnappers and murderers, violent men doing violent deeds, often using parliament as a front and excuse.

From 1603 to 1945, Members Behaving Badly tells the story of our nation through fifty-two of these parliamentary rogues. These are the MPs who made history – for all the wrong reasons.

From rake and poet Sir Charles Sedley, whose illicit partying while sozzled and stark naked caused a sensation even in Restoration London, to the stock-jobbing, flip-flopping chancellor of the Exchequer Charles Townshend, who proposed taxes that sparked a revolution, to David Lloyd George, Britain’s saviour during the First World War, but whose avarice, corruption, and abuse of honours ruined his political party forever, this is the story of the schemes and scandals of those members who behaved very badly indeed.

This is the history of Britain as you’ve never heard it before.

Portrait of Professor Frank McDonough

'This witty and well-written book highlights 52 parliamentary rogues from 1603 to 1945. There are fascinating stories of blackmail, adultery, embezzlement and murder. It’s a rattling good read.'

Author of The Hitler Years

Portrait of Jonathan Healey

'A thoroughly entertaining gallop through four centuries of Parliamentarian perfidy. Members Behaving Badly is a Hogarthian gallery of rogues and rotters, full of the woeful and riotous tales of the many men who have disgraced the benches of Westminster. I enjoyed it very much.'

Author of The Blazing World

Portrait of Charlie Higson

'Thought the likes of Johnson, Hancock, Pincher and Parish were the worst behaved MPs of all time? Think again … Funny, eye-opening and jaw-dropping.'

Portrait of Kate Vigurs

Portrait of Roger Moorhouse

'A riot of malfeasance and misbehaviour… Debbie Kilroy reminds us that, though we might imagine ourselves ill-served by our current crop of MPs, some of their predecessors were hilariously and horribly worse.'

Portrait of Jackson Van Uden

'Relevant, informative and timely, Kilroy shows us the real unparliamentary behaviour of the past, whilst also reminding us some things never change!'
