India, Sept. 14 -- Tesla CEO Elon Musk joined one of the largest far-right rallies in Britain on Saturday, addressing a crowd of more than 100,000 people in central London by video link as clashes between protesters and police left 26 officers injured and 25 people under arrest.

The event, branded "Unite the Kingdom" and organised by far-right activist Tommy Robinson, saw demonstrators march over Westminster Bridge before gathering near Downing Street for speeches from far-right figures across Europe and North America.

Other speakers included French politician Eric Zemmour and Petr Bystron of Germany's anti-immigrant AfD, both of whom invoked nationalist themes and conspiracy theories such as the so-called "Great Replacement."
