Social Democrat MP Benediktas Juodka, chairman of the committee, told BNS on Tuesday that the committee's meeting would be held after receiving conclusions from the Foreign Ministry's Inspectorate General.
"We will attempt to hold the meeting if we manage to convene the members of the committee," Juodka said.
Foreign Minister Linas Linkevičius has pledged that a proposal regarding the ambassadors would be submitted on Wednesday, based on the conclusions of the investigation.
Three members of the committee – Conservative Audronius Ažubalis, Liberal Petras Auštrevičius and Andrius Mazuronis of the Order and Justice party – have demanded to hold the meeting.
"Under the Seimas statute, a committee has to hold an extraordinary meeting upon the demand of at least one third of its members. This is the case now," Ažubalis told BNS.
In his words, the committee should be briefed on the investigation of the Inspectorate General and ways of ensuring safety of diplomatic conversations.
Ažubalis, Lithuania's former foreign minister, also said that ambassador could not be recalled without the committee's approval.
Earlier this week, Prime Minister Algirdas Butkevičius stated after meeting with President Dalia Grybauskaitė that the ambassadors whose conversations were leaked online have lost the trust of state leaders.
Under Lithuania's Constitution, diplomatic envoys abroad are appointed and dismissed by the president.
Grybauskaitė's spokeswoman said on Monday that decisions would be made based on the conclusions of the Foreign Ministry.
Last month, recordings of several phone conversations were published on youtube.com, allegedly involving Lithuania's ambassadors to Azerbaijan and Hungary speaking to diplomats and businessmen in Vilnius. In the recordings, the men share informal personal insights on the relations between Azerbaijan and Armenia, Prime Minister Algirdas Butkevičius' visit to Russia, and other topics.
After the leak, the Foreign Ministry received resignation from Ambassador to Azerbaijan Artūras Žurauskas. The foreign minister, Linkevičius, told journalists on Monday that Ambassador to Hungary Renatas Juška had not tendered resignation.
Lithuania's top officials have dismissed the leak as a provocation.
