Princess Kate attends Trooping the Colour with Prince William at the event as anti-monarchist protesters boo the royals. Multiple outlets report that Kate is present alongside the children Prince George, Prince Louis and Princess Charlotte during the public parade, with William on horseback. During their appearance, the group is met with boos from members of Republic, a campaign group that opposes the monarchy.
According to the reports, Republic stages a demonstration near the parade, including the use of umbrellas displaying the message “Stop The Reign.” Outlets describe Kate’s reaction during the booing, noting that she appears to stare toward the protesters while the event continues.
The coverage focuses on the contrast between the ceremonial nature of Trooping the Colour and the protest activity. No sources provided here describe injuries or arrests. The reports characterize the incident as a public demonstration and crowd reaction during the King’s official birthday parade.
