The chapter presents an empirically original account of the evolution of UK Labour Party international development policy, and Africa’s place within that, in the Party’s years of opposition from 2010–17. The chapter explores the significant processes of policy development which took place during these years and draws on archival research and interviews with key politicians. It argues that the Party has used the Sustainable Development Goals and a renewed focus on inequality to move policy beyond the Blair–Brown era. The chapter identifies constraints on this policy rethinking, including internal party politics and processes, rapid turnovers of shadow secretaries of state and an increasingly hostile external environment. Continuing tensions in policy remain to be resolved if Labour is to meet the challenge of developing an effective left-of-centre policy programme for Africa.
