In 1974, the government established the Diamond Commision on the Distribution of Income and Wealth. This note looks at the Commission’s findings and considers how Britain has changed in the intervening years. It looks at the impact the findings had on policy and public debate in the country and reflects on what can be learnt by those trying to secure a more equal Britain today. This project was undertaken as part of the Historians in Residence programme, which is based at King’s College, London.
