The dozens of detentions around the crowning of King Charles III intensified a national debate about new legislation that broadens police powers to arrest and charge potential demonstrators.
Supporters of an elected head of state for Britain see the coronation as an opportunity to highlight the absurdity of having a royal family in the 21st century.
King Charles III is less popular than his mother, offering republican campaigners their best chance of momentum in years. But they risk offending mourners by moving too soon.
