Former BBC director general Mark Thompson has said tonight: "The first questions I want to answer are ones from the MPs and to put Parliament first".
Mr Thompson said he had "made a submission" to the Public Accounts Committee and did not want to make any public statements ahead of his appearance before MPs on Monday.
He has accused BBC Trust boss Lord Patten and trustee Anthony Fry of "fundamentally misleading" the committee in July when they gave evidence on senior staff payouts at the corporation.
The BBC's head of HR, Lucy Adams, has admitted making a mistake in her evidence to a committee of MPs investigating excessive payoffs.
A spat has broken out between ex-BBC chief Mark Thompson and the Trust over large payoffs to departing staff.
