Red-faced council officers got into a right royal pickle when placing an advert for traffic arrangements and road closures for the forthcoming coronation.
Instead of King Charles III being crowned in May this year they mistakenly said the coronation was for King George III.
Of course there has already been a George III – who reigned from 1760 until his death in 1820.
Or it could have been confused with Prince George – the eldest child of Prince and Princess of Wales.
This would have meant the young prince, second in line to the throne, would have leapfrogged over his father, King Charles' eldest son and the heir apparent, to rule the nation.
The blunder in the public notices section of Thursday's Medway Messenger was spotted by a sharp-eyed reader.
KentOnline pointed out the mistake to the council, who reacted promptly to resolve the matter.
A Medway Council spokesman said: "We apologise for the error in last week’s public notices. As soon as we became aware we arranged for it to be amended online and will be republishing the correct notice in this week’s paper.
"We are looking forward to celebrating the coronation of His Majesty The King, Charles III, with residents in May.”
King Charles will be crowned alongside Camilla, the Queen Consort on Saturday, May 6 at Westminster Abbey.
Street parties are being planned across Medway for the bank holiday weekend.
You must apply for a road closure if you want to hold a street party. This is so the event can take place in a safe, closed environment.
Low traffic residential roads are those most likely to be suitable.
The council is waiving the normal £100 road closure fee so residents can apply to close a road on one day free of charge.
Before applying, people should consult with neighbours and collect a list of names and addresses of those who support and object to the street party and this information will need to be included in the application.
Residents will not need a licence to cook on the street or to play music, providing the music or entertainment is not advertised in advance to attract people to the party and organisers are not making any money from the event.

The closing date for applications is Friday, March 3.
