Seks said parliament and Croatian Radio Television were negotiating a live broadcast of the debate.
Parliament is expected to confirm the decision of the Credentials and Privileges Commission to strip Glavas of his parliamentary immunity and confirm his detention on suspicion of influencing witnesses in the investigation into his involvement in the Garage Case, requested by the Zagreb County Court, and a request for an investigation into Glavas's involvement in the Sellotape Case, launched by the Osijek County Prosecutor's Office.
Both cases refer to the killing of Serbs in Osijek in 1991.
The last parliamentary session in 2006 will last five weeks, namely until 15 December, when the constitutional deadline for regular parliamentary sitting expires.
The speaker said deputies were also expected to discuss a draft state budget for 2007.
The agenda of the 23rd sitting has 39 items and the government is expected to send another 20 bills, mostly concerning the adjustment of Croatia's legislation with EU standards.
