The BBC committed a "significant breach" of media regulations by failing to disclose that the presenter of a film about Gaza was the child of a Hamas official, as determined by UK media regulator Ofcom.
An probe by Ofcom into the documentary titled Gaza: How to Survive a Warzone has concluded that the programme was "significantly deceptive".
The chief executive of the broadcaster had previously apologised, stating there had been "a significant failing in relation to accuracy".
The regulator has ordered the corporation to transmit a peak-time declaration about its decisions.
"Given this constitutes a major infringement of our regulations, we are directing the corporation to broadcast a announcement of our conclusions against it on BBC Two at 21:00, with a date to be determined," it said.
'Potential to Undermine Credibility'
The regulator's statement declared: "Our probe concluded that the programme's failure to disclose that the voice's parent held a post in the Hamas-controlled government was substantially inaccurate.
"This implied that the audience did not have critical information which may have been extremely pertinent to their assessment of the voice and the information he provided.
"Credibility is at the heart of the relationship between a broadcaster and its public, notably for a state-funded media outlet such as the British Broadcasting Corporation.
"This oversight had the risk to damage the very considerable amounts of trust that the public would have placed in a factual film from the broadcaster about the Gaza conflict."
The film was withdrawn from the online platform in February after the presenter's personal associations were revealed, and in the month of July an broadcaster's internal assessment concluded it violated the organization's content policies on accuracy.
A corporation official commented: "The regulator's decision is in agreement with the findings of Peter Johnston's review, that there was a serious error in the programme in relation to the corporation's content standards on accuracy, which corresponds to regulation 2.2 of the authority's broadcasting regulations.
"We have apologised for this and we agree with the regulator's ruling in its entirety. We will comply with the directive as soon as the date and wording are finalised."
