Dyke has been called by Lord Hutton to give evidence at the inquiry. Lord Hutton has already heard from the BBC reporter at the centre of the debate, Andrew Gilligan.
It was Gilligan who claimed that the former Number 10 communications chief Alastair Campbell had "sexed up" an intelligence dossier on Iraq, which has since been found not to be true.
Campbell has been cleared by the Intelligence and Security Committee of embellishing the dossier to make a more compelling case for going to war on Iraq.
The Labour MP Gerald Kaufman said during a television interview that Dyke should apologise for the report, because there was no evidence to back up the claim that the report was embellished or sexed up.
When asked what Dyke should tell the inquiry, Kaufman told GMTV: "I'm sorry, we should not have done it. We are going to make sure that things like that never happen again in the BBC. The 'Today' programme has got out of control."
The BBC has remained supportive of Gilligan's report, which has led to a massive rift between the government and the corporation.
The Hutton Inquiry has been set up to urgently investigate the circumstances leading to the suicide of the government weapons expert Dr Tom Kelly, who died in July.
Other witnesses to appear today include former chief of defence intelligence Air Marshal Sir Joe French, and former deputy chief of defence intelligence security staff Tony Cragg.
