Protesters detained and arrested during UK coronation events.

Thousands of protesters gathered in London to protest against the monarchy on the day of King Charles III's coronation. At least seven people were detained by police on suspicion of breaching the peace. The anti-monarchy group Republic's leader, Graham Smith, was reportedly among those detained. The group's goal is to abolish the monarchy and replace it with an elected head of state. Polls show that Charles is less popular than his mother, sister, son, and daughter-in-law. Experts say that the monarchy's relevance is also at stake, particularly among young people, and family scandals have not helped matters.
