Democracy is in crisis, and unaccountable and untraceable flows of money are helping to destroy it.

Politicians lie gleefully, making wild claims that can be shared instantly with millions of people on social media. Donald Trump, Boris Johnson, Jair Bolsonaro and populists in many other countries are the beneficiaries.

Peter Geoghegan is a diligent, brilliant guide through a shadowy world of dark money and digital disinformation stretching from Westminster to Washington, and far beyond.

He shows how antiquated electoral laws are broken with impunity, how secretive lobbying bends our politics out of shape, and how Silicon Valley tech giants have colluded in selling out democracy. Geoghegan investigates politicians, fabulously well-funded partisan think tanks, propagandists who know how to game a rigged system, and the campaigners and regulators valiantly trying to stop them.

Democracy for Sale is the story of how money, vested interests and digital skulduggery are eroding trust in democracy - and a powerful account of what must be done about it.
