BBC chairman Samir Shah is set to offer up an apology to MPs today after his director-general Tim Davie resigned.
Mr Shah will release a written statement to the Culture, Media & Sport Committee - just hours after Donald Trump cast shade on the UK-US "special relationship" because of the BBC.
A Panorama documentary was found to have misled viewers by editing a speech by Mr Trump.
"The top people in the BBC... are very dishonest people who tried to step on the scales of a Presidential election," he said. "On top of everything else, they are from a foreign country, one that many consider our number one ally. What a terrible thing for Democracy!"
Mr Shah is expected to apologise and provide further details on the Panorama furore on Monday in front of the committee, which asked how he would address the concerns.
Mr Shah said Sunday was a "sad day" for the BBC while committee chairwoman Dame Caroline Dinenage said Mr Davie's resignation was "regrettable".
Dame Caroline's committee had earlier warned Mr Shah the broadcaster had "serious questions to answer" about the Panorama row, and asked him what action was being taken.
The committee is also set to meet tomorrow to consider the BBC's response and work out its "next steps".
It can ask witnesses to give evidence in person - and if they are not satisfied, Mr Shah may be called in for a physical grilling.

Labour minister insists BBC is 'very trusted' amid bias claims
Government minister Louise Sandher-Jones said the BBC is "very trusted" amid bias claims.
The veterans minister told Sky News: "When you look at the huge range of domestic issues, local issues, international issues, that it has to cover, I think its output is very trusted.
"When I speak to people who’ve got very strongly held views on those, they’re still using the BBC for a lot of their information, it’s forming their views on this.
“I think we can all point to elements of BBC broadcasting of news and say ‘well, that reflects my views, and that doesn’t’ and that’s absolutely right, that we should be able to say that."

Liz Truss has called for the "end of nationalised broadcasting" as she delivered her verdict on the BBC.
The former Prime Minister responded to a post by Donald Trump on X, in which he accused the BBC of trying to "step on the scales of a Presidential Election" after a leaked memo claimed the broadcaster edited a speech by the President earlier this year.
Ms Truss wrote: "I'm glad the US President and the rest of the world are seeing the BBC for what it is.
"Its failure to tell the truth on everything from transgender ideology to economics to Gaza has done huge damage to politics and government in this country.
"This should be the end of nationalised broadcasting."

TODAY'S TOP STORY: BBC boss Tim Davie resigns after 'systemic bias' row and admits broadcaster 'is not perfect'
BBC director-general Tim Davie and BBC News CEO Deborah Turness resigned last night - the latest twist in a calamitous week for the national broadcaster.
A Panorama documentary was found to have misled viewers by editing a speech by US President Donald Trump - sparking fury from in Britain and the US.
Mr Davie oversaw a slew of controversies at the licence fee-funded broadcaster - including multiple in 2025 alone, where it broadcast "death to the IDF" chants at Glastonbury and shared a Gaza "documentary" starring the son of a senior Hamas official.
In his resignation letter, the disgraced director-general claimed the BBC "is of unique value and speaks to the very best of us".
Though in Washington, Donald Trump and the White House appeared to disagree.
"Thank you to The Telegraph for exposing these corrupt 'journalists'," he said. "These are very dishonest people who tried to step on the scales of a Presidential election."
White House Press Secretary Karoline Leavitt instead urged "everyone" to watch GB News.
