Social democrat Adomavičius said at the commission meeting that accusations against him "have a very obvious political basis" but he did not object to losing his legal immunity.
"I am ready to take part in the process as much as I can and I do not plan to hide," he said, adding that "the case has a very clear political basis and was opened two weeks before the elections."
Prosecutors carrying out a pre-trial investigation on alleged bribery had asked the commission to cancel Adomavičius' legal immunity.
The Special Investigation Service and Vilnius Regional Prosecutor's Office are carrying out an investigation into bribery and trade in influence. Adomavičius is suspected of having accepted a bribe of 32.5 thousand litas in exchange for a promise to influence municipal staff so they made a favorable decision in a public tender for services worth 8 million litas (EUR 2.32 million).
Searches were conducted in the vice-mayor's office at Vilnius Municipality, at the headquarters of Vilnius Unit of the Social Democratic Party of Lithuania and at company Vilniaus Vandenys (Vilnius Waters) on Thursday. Money was taken from Adomavičius but suspicions were not brought against him as he had legal immunity as a candidate in the upcoming Seimas elections.
Adomavičius denies all accusations and says the money found by investigators was his personal money meant for the election campaign.
The vice-mayor later withdrew from his official position at Vilnius Municipality and suspended his party membership.
Adomavičius is currently running for parliament and has legal immunity. He is number 48 on the Social Democratic Party's list and is also a candidate in Lazdynai single-member constituency.
