The 2010 General Election was a watershed moment for the Labour Party. The transition from government to opposition was abrupt, and for Sadiq Khan, it marked the beginning of a period of deep introspection and strategic rebuilding. After five years of being in the engine room of government, he was suddenly on the sidelines, tasked with helping his party find its voice in a post-Brown, post-financial crisis era.
These were the "wilderness years." While the public often views opposition as a time of inaction, for a politician like Sadiq, it was a time of immense labor. He was appointed to the Shadow Cabinet, serving as Shadow Secretary of State for Justice. This role was a natural fit for a man who had spent his early career as a human rights lawyer. He stood across from the government benches, holding Ministers to account on legal aid cuts, prison reform, and the integrity of the judicial system.
In the face of the coalition government’s austerity measures, Sadiq’s work became increasingly focused on the human cost of policy. He saw how the legal aid changes were effectively shutting the doors of justice to the poorest in society—a direct reversal of the very principles he had fought for as a solicitor. His speeches during this time grew sharper, more focused on the intersections of inequality and the law.
But these years were also a test of political loyalty and endurance. The party was wrestling with its identity, moving through leadership changes and shifting priorities. Sadiq learned the importance of party management, often acting as a bridge between the party’s traditional base and its more metropolitan, progressive wings. He became a key figure in the party’s electoral machinery, serving as Ed Miliband’s campaign manager for the 2015 general election. The crushing defeat in that election was a personal and professional blow, a moment of profound disappointment that forced him to rethink his own political future. He had poured everything into the campaign, only to watch the party falter. It was in the quiet of that aftermath that the idea of the Mayoralty began to take hold.
