Sadiq Khan is the new mayor of London after gaining 1.31 million votes to Zac Goldsmith's 994,614.
During his acceptance speech at City Hall in the early hours of Saturday morning, the Labour candidate thanked Londoners for choosing "hope over fear, and unity over division", a nod towards Goldsmith's controversial campaign.
But the message was lost on far-right Britain First leader and mayoral candidate Paul Golding, who turned his back while Khan, the first Muslim to become mayor of a major European capital, was talking.
Golding told BuzzFeed News his one-man protest was not racist, but that he acted as he did because Khan was "vile".
Regardless, his intervention has gone down as well as expected.
