The British branch of the global campaigning organisation held a social event to celebrate the 10th anniversary of the Human Rights Action Centre, its headquarters in London's fashionable Shoreditch district.

Kaiser Chiefs frontman Wilson posed with a campaign banner outside the event, and Game of Thrones star Oona Chaplin flashed a peace sign for snappers.

The party was also attended by actor Ryan Gage, Snow Patrol singer Gary Lightbody, Sir Mick Jagger's ex-wife Bianca Jagger, and Rocky Horror Show creator Richard O'Brien.
