Regional inequality is increasingly shaping contemporary politics in the UK. However, London is commonly taken as the yardstick against which the welfare of other areas should be judged where wealth and prosperity are concerned. The reality is that London is riven by inequality, with millions of people living in poverty. This collection brings together contributions from geography, politics and sociology, and from politicians, academics and think tanks. It explores how inequality manifests itself in London through housing and planning reform, the legacy of levelling up and shifts in the electoral loyalties of different ethnic groups, showing the perils for both London, the present government and the rest of the UK of leaving inequality in the capital unchecked.
