Thousands of people, including former British Prime Minister Boris Johnson, gathered in London on Sunday for a march against antisemitism. The march took place a day after large crowds turned out for a pro-Palestinian rally. Boris Johnson was joined by the UK’s Chief Rabbi Ephraim Mirvis and other senior government officials to show support for the Jewish community and express solidarity against antisemitism. The organizers of the march stated that it was the largest gathering against antisemitism in London in decades. During the march, participants waved Israeli and the UK’s Union flags and held placards with slogans such as “Never Again Is Now” and “Zero Tolerance for Antisemites”. However, there were some clashes between counter-protesters and the police, resulting in the detention of Stephen Yaxley-Lennon, also known as Tommy Robinson, the former leader of the far-right English Defence League. The police detained Yaxley-Lennon after he refused to leave the area, citing concerns about potential harassment, alarm, and distress to others. Gideon Falter, the chief executive of Campaign Against Antisemitism, commented on the rally, stating that it followed weeks of pro-Palestinian protests that had made the capital a “no-go zone for Jews”. On the previous day, tens of thousands of pro-Palestinian protesters had marched to demand a permanent cease-fire in the Israel-Hamas war.
