The 74-year-old monarch was escorted away from the large crowd by security personnel.
Charles didn’t crack up after the egg incident and kept his sunny disposition shaking hands with members of the public after he was relocated.
Since the death of his mother, Queen Elizabeth II, King Charles has been touring Britain making public appearances. He plans to visit several places in Luton, including a transit station and a Sikh house of worship – a gurdwara.
But this isn’t the first time someone has thrown an egg at King Charles.
When Charles and Queen Consort Camilla arrived in York for an official visit in November, a protester pelted her with a few eggs.
Demonstrator – disclosed Annihilationist activist and former Green Party candidate Patrick Thelwell’s “This country was built on the blood of slaves!”
Thelwell, 23, is now reportedly banned from carrying eggs in public.
