Anti-monarchy campaigners from Republic have announced they will stage protests at this weekend's Trooping the Colour ceremony for the second consecutive year.
The demonstrations are being held in protest against the Royal Family and the institution of monarchy.
The protest group has specifically criticised King Charles, Prince William, Prince Edward and Princess Anne for wearing military ranks and medals.
The campaigners plan to maintain a presence throughout Saturday's ceremonial event in central London.

Graham Smith, Republic's CEO, said: "Charles does not qualify for any of the medals he wears.
"He has not earned the ranks he wears; he was promoted in all the services as birthday presents from his mum."
Smith added: "Edward and Anne haven't served a day in the armed forces, yet they, too, dress up. Their behaviour is an insult to the bravery of our military."
Despite these claims, King Charles served with the aerial force in 1971 and became a fully qualified helicopter pilot in 1974.
Republic is known for its planned protests during royal events.
PAThe King also served in the military during the 1970s, retiring in 1976; however, he has kept a close relationship with the RAF and holds the highest titles in the regiment.
In addition, Princess Anne is committed to her military causes and is often at engagements supporting these affiliations every year.
Meanwhile, Prince Edward spent three years in the Royal Marines as a University Cadet, and Prince William served in the Army with the Blues and Royals and as an RAF search and rescue pilot.
Three years as a search and rescue pilot saw the Prince of Wales conduct 156 operations, take on routine operational deployment to the Falkland Islands and qualify as an operational Captain.
Smith compared his upcoming protests with similar events in the United States, stating: "US citizens have very real concerns about Trump's actions and his military parade.
Kate made her first return to the spotlight at Trooping the Colour last year.PA"Here in the UK, we have the real deal, a King who dresses up in unearned uniforms and medals and insists on a huge military parade through London."
Protesters will begin gathering from 8:30am on Saturday morning and remain until the 1pm flypast concludes the ceremony. Organisers from Republic will arrive at 6am to prepare for the demonstration.
The protests form part of Republic's sustained campaign against royal events, which has been ongoing since before the Coronation over two years ago.
The group staged demonstrations in Hexham and Lancaster just last week when the King and Queen visited those locations.
Smith said: "Trooping the Colour is the key iconic royal event of the year. From now on, there will be protesters there, calling out the event and the monarchy as a superficial cover for a grubby and corrupt institution."

GettyRepublic has highlighted that hundreds of military veterans are among its membership, describing them as "people who have been willing to defend country, not King."
Smith concluded with a warning about the group's future plans: "Support for the monarchy is falling, and protests will continue at all major royal events until it has been abolished."
Despite Smith's claims, Prince William scored a 75 per cent approval rating from Britons in the latest YouGov poll, while Princess Kate has a 72 per cent approval rating.
When it comes to King Charles III, 61 per cent of Britons have a positive view of the current monarch, compared to just 29 per cent with an unfavourable view.
