Turning Point USA has confirmed plans for its founder Charlie Kirk's funeral.

Mr Kirk was shot dead at 31 on Wednesday while hosting a debate event at Utah Valley University in an attack which has sent shockwaves around the world.

Now, the organisation he set up at 18 has outlined how thousands will gather to remember him.

Supporters have been invited by Turning Point to State Farm Stadium, the 63,000-capacity home of the Arizona Cardinals American football team, on September 21.

On Friday, President Donald Trump confirmed he would be in attendance.

He had earlier ordered all American flags to fly at half-staff from Wednesday until Sunday at 6pm.

Turning Point's "Building a Legacy: Remembering Charlie Kirk" website includes a lengthy tribute to the "American legend".

His "life was a testament to faith, courage, and conviction", it says.

"From his earliest days, he believed America was worth fighting for."

"Charlie died doing what he loved: fighting for truth, for faith, for family, and for America," it continues.

"His sacrifice will endure as a guiding light for generations. Though our hearts are heavy, we do not grieve as those without hope.

"Charlie's legacy endures in his family, in Turning Point USA and Turning Point Action, and in the millions he inspired to live with conviction."

His widow Erika, who was seen crying as JD Vance and US servicemen carried Mr Kirk's coffin aboard Air Force Two just days ago, also paid tribute to her husband.

Mother-of-two Ms Kirk, who married the conservative influencer in 2021, said: "I love you, I love you, I know, I miss you so much.

"They have no idea what they just ignited within this wife. If they thought my husband's mission was big now, you have no idea" she added in a caption.

"The world is evil," Ms Kirk also wrote on social media.

"The sound of this widow weeping echoes throughout this world like a battle cry. I have no idea what any of this means. But baby I know you do, and so does our Lord."

In London, hundreds of people attended a vigil for Mr Kirk by the statue of Field Marshal "Monty" Montgomery in Whitehall.

Jack Ross, the chief executive of Turning Point UK, an off-shoot of Mr Kirk's US campaign group, said: "Charlie was not a hateful far-right bigot: he was a good Christian man and his desire to help people came from his passion for Christ."

Then on Saturday, crowds marching as part of Tommy Robinson's "Unite the Kingdom" rally were seen holding pictures of the slain activist.

Before the 31-year-old's funeral, his suspected killer is set to face formal charges.

Tyler Robinson, 22, was finally arrested on Thursday after relatives and a family friend told authorities that he had implicated himself in the crime - bringing an end to a 33-hour manhunt.

The President said, if found guilty, he hopes Mr Robinson receives the death penalty.
