A far-right lawmaker from the Netherlands has joined thousands of people in central London to demand freedom for a British commentator who was jailed for contempt of court after he broadcast outside a criminal trial for the second time.

Video footage showed activists marching with "Free Tommy" placards and Dutch lawmaker Geert Wilders telling the crowd: "We will not be silenced." A small number of demonstrators pushed police and tried to breach metal barricades in front of the British prime minister's office.

The subject of the Saturday event was Tommy Robinson, the pseudonym of 35-year-old Stephen Yaxley-Lennon. Robinson founded the English Defence League, an anti-Muslim protest group. He was arrested May 25 after livestreaming from outside a child sexual exploitation trial.

Reporting restrictions were in place for the trial to protect jurors' impartiality.
