A senior British lawmaker asked Prime Minister Keir Starmer on Monday to consider sanctions against Elon Musk after the Tesla chief delivered a video address to a far‑right, anti‑migrant rally in London that police say left dozens of officers injured.

Liberal Democrat leader Ed Davey wrote in a public letter that Musk attempted to "sow discord and incite violence" with remarks delivered to the "Unite the Kingdom" demonstration organized by far‑right activist Tommy Robinson. Musk told the crowd via video link that "violence is coming to you" and that people must "either fight back or you die," and he blamed "massive uncontrolled migration" for what he described as the "destruction of Britain."

In his letter to Starmer, which was also sent to Conservative leader Kemi Badenoch and Reform UK leader Nigel Farage, Davey urged political leaders to "put party politics aside and join me in publicly condemning these dangerous remarks, and to jointly consider what sanctions Elon Musk should face as a consequence." Davey added that freedom of speech and the right to peaceful protest must be upheld but said that no individual should be able to use a platform to inflame tensions or incite violence.

Musk, who owns the social platform X and has frequently commented on British politics, responded on social media after Davey publicized the letter, calling the lawmaker a "craven coward." Downing Street directed media inquiries to a post by Starmer condemning assaults on officers and asserting that people have a right to peaceful protest, saying: "We will not stand for assaults on police officers doing their job or for people feeling intimidated on our streets because of their background or the colour of their skin." Starmer has not publicly replied to Davey's request to consider sanctions.

The Metropolitan Police said up to 100,000 people attended Saturday's demonstration and reported that 26 officers were injured and at least 25 people were arrested. Assistant Commissioner Matt Twist said a post‑event investigation was under way and that further arrests may follow. Photographs and video from the rally showed participants carrying anti‑immigration placards with slogans such as "send them home." Authorities have said the crowd included a mix of participants, and police described the scene as volatile at times.

The rally comes amid heightened public and political tensions over migration policy in Britain. Over the summer, protests and disruption focused on a hotel in Epping, a town just outside London, that was housing asylum seekers. Local officials said the site experienced "unprecedented levels of protest and disruption," and a judge in August ordered the asylum‑seekers to be reallocated.

Davey's letter frames Musk's intervention as part of a broader pattern of political engagement by a high‑profile social media owner whose posts and platform decisions have increasingly shaped public debate in the U.K. and abroad. It requests coordinated condemnation from party leaders and consideration of potential consequences, but it did not specify what legal measures or specific sanctions should be pursued.

Home Office and government officials did not immediately set out any next steps for sanction considerations. Police officials said they would continue the investigation into the demonstration, review evidence and consider appropriate follow‑up, including potential prosecutions.

The episode spotlights ongoing questions about the responsibilities of prominent, wealthy individuals who address mass political gatherings from afar and about how governments should respond when such interventions intersect with public order and community tensions. It also underscores the continuing salience of migration as a deeply polarizing issue in British politics and the strain it places on law enforcement and local communities.
