Charlie Kirk's UK campaign group paid tribute to the Conservative activist in front of the Montgomery Statue in Whitehall on Friday after he was assassinated at Utah Valley University by a single shot to the neck.
The vigil, which was organised by the British branch of the right-wing political organisation founded by Mr Kirk Turning Point UK, urged its followers to 'Join us in remembering Charlie' on X.
Speaking to a crowd of just under 500 people, Turning Point UK CEO Jack Ross said: 'Thank you everyone for coming here today.
'I know Charlie would have been incredibly touched by your presence.
'I would like to also thank members of the United States law enforcement who have successfully apprehended Charlie's murderer.
