The protests in London recently took place mainly in Central London around Whitehall, Westminster, and nearby areas. The far-right "Unite the Kingdom" rally led by Tommy Robinson gathered between 110,000 to 150,000 people starting around Stamford Street near Waterloo Bridge, and extended into Whitehall and Parliament Square as the crowd was too large to fit into those areas. Participants moved towards areas such as Bridge Street, Westminster Bridge, Victoria Embankment, Horse Guards Avenue, Whitehall Place, Northumberland Avenue, and Craven Street during the event. A counter-protest called the March Against Fascism, organized by Stand Up To Racism, gathered about 5,000 people mainly around Russell Square before marching towards Whitehall. The protests saw heavy police presence and confrontations occurred when some protesters tried to breach police barriers separating the two groups in these central London locations. Riot police, horses, and dogs were deployed to manage the crowd and attempts to access "sterile areas" between the protests.
In summary, the protests happened centrally in London mainly around Whitehall, Westminster, Parliament Square, and surrounding streets, with counter-protests concentrated around Russell Square to Whitehall.
