Prince William has cancelled tomorrow’s engagement as Buckingham Palace issued a statement.
Earlier today, the Royal Family announced that engagements will be postponed following the Prime Minister’s statement calling for a general election.
Following this guidance from Buckingham Palace, the Prince of Wales has postponed unannounced public activities planned for Thursday.
The King has also postponed his engagements for the rest of this week as the royals don't want to divert attention away from the election campaign.
A Buckingham Palace spokesperson said: “Following the Prime Minister’s statement this afternoon calling a General Election, The Royal Family will – in accordance with normal procedure – postpone engagements that may appear to divert attention or distract from the election campaign.
“Their Majesties send their sincere apologies to any of those who may be affected as a result.”
The statement said engagements that "may appear to divert attention or distract from the election campaign" will be cancelled.
However, GB News Royal correspondent Cameron Walker said on X: "I understand D-Day memorial engagements will go ahead, but others will be reviewed on a case by case basis."
It is not confirmed whether Trooping the Colour, scheduled for June 15, will still go ahead or if the King will still host the Emperor and Empress of Japan planned for late June.
July 4 also falls within Holyrood Week when the King is due to visit Scotland, but this could be cut short for Charles to be at Buckingham Palace on July 5 to appoint his Prime Minister.
On Wednesday afternoon, Rishi Sunak declared that the next UK general election will be held on July 4.
Before his announcement, the Prime Minister asked the King to proclaim the Dissolution of Parliament and the monarch complied with the request.
