Analysis: Richard Galpin, BBC world affairs correspondent
Dmitry Kovtun - who told me in an interview earlier this year that he had once been a member of the Russian army intelligence corps - had claimed he wanted to testify at the inquiry to refute much of the evidence linking him and the other chief suspect, Andrei Lugovoi, to the fatal poisoning of Alexander Litvinenko.
He also said he wanted to get access to the key documents which are made available to all core participants.
Sources close to the inquiry say Mr Kovtun will have been able to see sensitive documents, including some which have not been made public.
It's not clear yet how significant this could be, but it had been one of the main concerns about letting Mr Kovtun become a core participant.
There are also fears that if he ignores his last opportunity to give evidence on Tuesday morning, he will try to argue that he's been denied the chance to defend himself because of circumstances beyond his control.
And there could then be attempts to question the legitimacy of the inquiry.
