Elected members of the City of London Corporation have agreed to write to Andrew Mountbatten-Windsor inviting him to relinquish his freedom of the city.
The former prince received the honour in 2012, a spokesperson for the local authority said.
In a statement released on Thursday, a spokesperson said: “Andrew Mountbatten-Windsor received the freedom of the City of London in 2012 by virtue of patrimony, which is inherited as the child of a freeman and constitutes a legal right.
“Applications via patrimony are not considered or endorsed by our elected members, and there is no effective legal mechanism to remove this type of freedom.
“Elected members have today agreed to write to Mr Mountbatten-Windsor, inviting him to formally relinquish the freedom.
“They will consider the response received, if any, at a future meeting and determine what action may be taken.”
