Boris Johnson and several other British politicians have paid tribute to conservative activist Charlie Kirk after he was shot dead at Utah Valley University.
The political commentator, 31, took a single bullet to the neck while he spoke to a crowd on Wednesday afternoon.
Former British prime minister Johnson took to X to pay tribute to Kirk, who was considered a close alley of US President Donald Trump.
'The murder of Charlie Kirk is a tragedy, and a sign of the utter desperation and cowardice of those who could not defeat him in argument', he wrote.
'Charlie Kirk has been killed not for espousing extremist views - because he didn't. He has been killed for saying things that used to be simple common sense. He has been killed because he had the courage to stand up publicly for reasonable opinions held by millions and millions of ordinary people both in the US and Britain.
