The major protest event in London today, September 14, 2025, centers around the "Unite the Kingdom" march organized by far-right activist Tommy Robinson. This event attracted over 110,000 participants who marched through central London, particularly around areas such as Whitehall, Horse Guards Avenue, Whitehall Place, Northumberland Avenue, Craven Street, Westminster Bridge, and near government buildings like the Houses of Parliament and Big Ben. There was also a significant counter-protest of about 5,000 individuals organized by "Stand Up to Racism," primarily stationed around Whitehall, kept apart from the main march by police barriers. The situation turned confrontational in places where some protesters attempted to breach police barriers separating them from counter-protesters, resulting in clashes and injuries to police officers. The Metropolitan Police reported injuries to 26 officers and multiple arrests as part of ongoing efforts to manage and investigate the disorderly conduct during the protests. Police have been using mounted units, dogs, and protective gear to control the crowds. The protest locations have extended beyond Whitehall into adjoining streets due to the vast size of the rally.

In summary, current London protests today are mainly concentrated in central London around Whitehall and nearby key government and public landmarks, with active police presence managing the large and volatile crowds.
