The King and Queen Consort have postponed their state visit to France following violent protests in the country.
The royal couple were due to travel on Sunday but the trip will be rescheduled as soon as possible, the French president’s office said.
The decision was made after a phone call between Emmanuel Macron and King Charles, reported The Sun.
