The BBC committed a "significant breach" of industry standards by not revealing that the presenter of a documentary about the Gaza conflict was the son of a Hamas official, according to UK media regulator Ofcom.
An inquiry by the media regulator into the programme Gaza: How to Survive a Warzone has concluded that the documentary was "substantially inaccurate".
The BBC's director general had previously apologised, stating there had been "a major oversight in relation to truthfulness".
Ofcom has directed the BBC to air a prime-time announcement about its findings.
"As this represents a serious breach of our regulations, we are directing the BBC to air a statement of our determinations against it on BBC2 at 9pm, with a timing to be finalised," the statement read.
'Risk to Damage Credibility'
The watchdog's report declared: "Our investigation determined that the programme's lack of disclosure that the narrator's father held a role in the Hamas-controlled government was substantially inaccurate.
"It meant that the public did not have critical information which may have been very significant to their assessment of the presenter and the content he presented.
"Credibility is at the heart of the bond between a television network and its public, particularly for a national broadcasting corporation such as the BBC.
"This error had the potential to undermine the very considerable amounts of trust that the public would have put in a BBC factual programme about the conflict in Gaza."
The documentary was removed from iPlayer in the month of February after the presenter's familial connections came to light, and in the month of July an corporation's own inquiry concluded it violated the broadcaster's journalistic standards on accuracy.
A corporation official commented: "The regulator's decision is in accordance with the findings of Peter Johnston's review, that there was a serious error in the film in relation to the corporation's content standards on factual correctness, which aligns with Rule 2.2 of the regulator's media standards.
"We issued an apology for this and we comply with Ofcom's decision in full. We will comply with the directive as soon as the date and wording are confirmed."
