Billionaire Elon Musk on Thursday called for the release of a British far-right activist in jail for spreading false allegations about a Syrian refugee schoolboy.

“Free Tommy Robinson!” Musk, the world’s richest man, wrote on X, the social media platform he owns.

Robinson, whose real name is Stephen Yaxley-Lennon, was sentenced in October to 18 months in jail for violating a court order stemming from a successful libel case brought by Jamal Hijazi, who had been videotaped while being attacked at school, the Guardian reported.
