The Bloody Sunday inquiry is set to reconvene a month after it came to a formal end so it can hear the evidence of one more witness.
The inquiry wants to hear from a man known as Witness X.
Witness X, according to RUC notes dating back to 1972, told the inquiry he was a member of the Provisional IRA on Bloody Sunday and that in a joint operation with the Official IRA opened fire from the nationalist Bogside.
Witness X made a statement to the Bloody Sunday lawyers two years ago denying firing and being a member of the Provisional IRA.
The witness was issued with a subpoena last January ordering him to give evidence to Lord Saville but he did not attend, citing medical grounds.
Now Lord Saville is understood to have decided he needs to hear from him and is planning a sitting in the New Year.
