Many people came to London for two big marches. One group followed Tommy Robinson and wanted to "Unite the Kingdom." They walked with flags and listened to speeches. Another group, called Stand Up To Racism, came to say no to racism and no to hate. They held signs and listened to speakers too.

The police were there to keep the two groups apart. Some people tried to cross the police line, and some police officers were hurt. The police told everyone to be safe and to follow the rules. They said they would stop anyone who did something wrong.

Some people in London were worried about the march. The police said everyone should feel safe and can ask police for help. The police asked people to be kind and to finish the marches at the right time.
