Breitbart London is the UK branch of the US media empire founded by Andrew Breitbart in 2005. At one point hugely influential in US right-wing politics, Breitbart helped to establish and cement the careers of far-right influencers such as Steve Bannon, Milo Yiannopoulos and Raheem Kassam. Breitbart has since lost ground to other far-right outlets in the US, however, and its UK branch never achieved the same prominence in the British media landscape as its parent company had in the US.

Breitbart London launched in 2014 with the explicit intention of importing US culture war issues to the UK, with then-Executive Chairman Steve Bannon telling the New York Times that they saw the UK as a “front in our current cultural and political war.” Adopting the then-ascendant UKIP as a political vehicle, Breitbart London – and particularly Raheem Kassam – played a key role in directing the party to diversify its platform from a singular focus on anti-Europe sentiment into a more overtly xenophobic and anti-establishment party.

As of 2023, the London operation is much-diminished in both stature and staff. Now sharing a landing page with the rest of Europe on the Breitbart website, it appears to have just a handful of staff covering the whole of the continent, churning out regurgitated articles originating in more mainstream outlets.
