King Charles is set to have greater security when completing the traditional walkabout after attending Christmas Day services at Sandringham due to fears of protests.

Royal chiefs are looking to urgently review how the new monarch interacts with the public after eggs werethrown at the King in York and Luton.

Video showed the King being ushered away from crowds as eggs landed on the floor.

A source from the palace household is reported to have told the Mirror: “This isn’t just about individuals with eggs, everyone is extremely aware it could be far worse.”

The source did not say what “far worse” could mean, but there were reports an intruder was able to get into Windsor Castle on Christmas Day in 2021 with a crossbow.

The King and family are now in Sandringham, their traditional base for the Christmas period, having held events at Windsor Castle this week in preparation.

All senior Royals are set to attend St Mary Magdalene church on December 25. The monarch has already recorded his first speech as King to be broadcast on Christmas Day.

Former Metropolitan Police chief ­superintendent and head of the royal protection unit Dai Davies told the Mirror: “We must defend the right to peaceful protest, but all officers and their superiors must have a razor-sharp focus in the wake of this increase in disturbance.

“There is no magic solution to this pattern of attacks or protests, but intelligence and exit strategies are the most important factor.”

While crowds have largely been supportive to the new monarch as he completes his duties, the former Prince of Wales was shouted at by a protestor in Cardiff.

“Charles,” the man yelled, “While we struggle to heat our homes we have to pay for your parade. The taxpayer pays £100 million for you, and for what?”
