"We have a very clear situation today (and) enough information to set up an impeachment commission," Gabrielius Landsbergis, the leader of the opposition Homeland Union–Lithuanian Christian Democrats, told reporters after the committee's meeting on Wednesday.
"That means that we, members of the committee, now have enough understanding and information pointing to a possible breach of oath," he said. "We decided to start collecting signatures today".
Social Democratic MP Dovile Sakaliene said that "there are sufficient grounds for members of the Seimas to ask for the establishment an ad hoc impeachment inquiry commission."
"There's no need to wait for the end of the investigation and of certain political games," she said. "We believe there's nothing to wait for anymore and we're starting to collect signatures."
CNSD Chairman Dainius Gaizauskas of the ruling Farmers and Greens Union said he would sign under the initiative, too.
"If the collection of signatures begins, this certainly has to be signed. This had to be done back in January 2018," he told reporters.
According to the chairman, an impeachment commission would conduct a separate investigation into whether there are grounds for initiating impeachment proceedings due to a breach of oath.
CNSD, meanwhile, is not only investigating Rozova's alleged ties with Russian diplomats and their possible national security implications, but is also looking into actions by Seimas officials who were provided with information about Rozova.
At least 36 signatures are necessary to initiate impeachment proceedings in the parliament.
The parliamentary investigation was initiated after it came to light that the State Security Department had recommended in its report to Viktoras Pranckietis, the speaker of the Seimas, that MP Rozova be denied access to classified information.
The report says that Rozova and Russian diplomats discussed financial support for her party, the Russian Alliance, and that she had contacts with Russian Consul General Vladimir Malygin who was sent out of Lithuania in 2014.
Rozova insists that her contacts with Russian diplomats were not personal and, therefore, she did not have to report them to the intelligence agency when applying for access to classified materials.
Rozova is a member of the Electoral Action of Poles in Lithuania – Christian Families Alliance's political group in the Seimas.
CNSD has until April 30 to conclude its investigation.
