The BBC was found to have committed a "significant breach" of industry standards by not revealing that the presenter of a documentary about the Gaza situation was the offspring of a Hamas administrator, as determined by British broadcasting authority Ofcom.
An inquiry by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "substantially inaccurate".
The head of the BBC had already issued an apology, stating there had been "a major oversight in relation to factual correctness".
The authority has instructed the BBC to air a prime-time announcement about its findings.
"As this represents a serious breach of our regulations, we are instructing the broadcaster to transmit a message of our conclusions against it on BBC2 at nine o'clock in the evening, with a date to be finalised," it said.
'Possibility to Undermine Credibility'
The watchdog's report stated: "Our investigation found that the film's omission to reveal that the voice's father occupied a position in the Hamas-run authority was substantially inaccurate.
"Consequently that the viewers did not have essential details which may have been extremely pertinent to their assessment of the voice and the details he provided.
"Confidence is at the center of the bond between a broadcaster and its viewers, especially for a public service broadcaster such as the BBC.
"This error had the possibility to erode the significantly high amounts of confidence that viewers would have put in a BBC factual programme about the Israel-Gaza war."
The documentary was pulled from the BBC's streaming service in last February after the presenter's personal associations emerged, and in this past July an corporation's own inquiry found it infringed the organization's content policies on factual correctness.
A BBC spokesperson commented: "The regulator's decision is in accordance with the results of the corporation's inquiry, that there was a serious error in the film in relation to the BBC's Editorial Guidelines on truthfulness, which corresponds to Rule 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we agree with the authority's determination in complete. We will comply with the directive as soon as the date and language are finalised."
