Comments follow remarks by Keir Starmer who is under pressure to be more proactive in defence of diversity

Downing Street has fiercely condemned Elon Musk for using “dangerous and inflammatory” language, after he told a crowd of protesters in London that “violence is coming” and “you either fight back or you die”.

Musk, the owner of the social media platform X, appeared via video link at the rally that left 26 police officers injured on Saturday. He spoke to the activist Stephen Yaxley-Lennon, known as Tommy Robinson, while thousands watched and listened.

Keir Starmer has been under pressure from his own MPs and anti-fascist groups to be more proactive in defence of diversity and speak out against some of the rhetoric used during what is thought to have been the largest nationalist event in decades.

Police estimate that between 110,000 and 150,000 people attended the event, organised by Robinson. At least 25 people were arrested and police faced a barrage of physical and verbal abuse from demonstrators who sought to breach cordons.
