The democratic campaign group Republic has challenged the BBC over its continuing role as what it describes as "propagandist-in-chief for the royal family".
The move follows news that the broadcaster is to show a four part series following Prince William in his job as a search and rescue helicopter pilot serving with C Flight of 22 Squadron at Royal Air Force (RAF) Valley on Anglesey.
Republic has previously accused the BBC of "fawning over the royals" and failing in its duty to present them in a fair and unbiased way.
The group will be contacting the new Director General to raise its concerns as to the manner in which the BBC continues to "promote the royals in a consistently flattering light."
Republic chief executive officer Graham Smith said today: “Prince William is a public figure who is in line to be head of state. As with all royals he should be dealt with by the BBC in an impartial and dispassionate way.
“It is not appropriate for the BBC to commission a piece of PR that will promote the image of the royals in an uncritical manner, putting William in the role of the hero.”
