The political sibling rivalry that once defined the British Cabinet

Cultures · Published 1 October 2026 Swipe more like this →

In short: In a rare moment of political history, two brothers sat together in the UK Cabinet. Ed and David Miliband did more than just share a family tree; they often served as the vital, sometimes tense, bridge between the warring factions of the Labour Party.

The Miliband brothers grew up in a household defined by intense political debate. Their father, Ralph Miliband, was a Belgian-born Marxist intellectual who fled to England in 1940, while their mother, Marion Kozak, was a Polish Jewish human rights campaigner who survived the Holocaust thanks to the protection of a Catholic family in Poland. This intellectual heritage shaped their respective paths in British politics.

The siblings' careers frequently intersected in ways that mirrored the internal struggles of the Labour Party. During the era of Prime Ministers Tony Blair and Gordon Brown, David served in high-ranking roles like Foreign Secretary, while Ed held positions such as Chancellor of the Duchy of Lancaster. On several occasions, the brothers acted as intermediaries to settle or calm disputes between the Blair and Brown factions.

Ed Miliband’s own leadership, spanning from 2010 to 2015, was marked by significant structural changes. He moved the party toward a 'one member, one vote' system and sought to reform how trade union contributions were handled. However, his tenure faced immense challenges, including a massive surge in the Scottish National Party's influence and a decisive defeat in the 2015 general election, which ultimately led to his resignation.

Despite the volatility of party leadership, Ed Miliband has remained a persistent figure in the UK's political landscape. From serving as the first person to hold the energy and climate change portfolio to his more recent roles in the cabinets of Keir Starmer and Andy Burnham, his career reflects the enduring shifts within the Labour movement.
