Previously both National Alliance, which has a single seat at the town's council, as well as President Raimonds Vējonis, formerly from the same party as Truksnis, asked for him to step down.
On Thursday the majority of the Jūrmala City Council voted that Truksnis cannot go on leading the municipality.
On October 4 Latvia's anti-graft squad, the Corruption Prevention and Combating Bureau raided the offices of the Jurmala municipality and mayor Gatis Truksnis of the Greens and Farmers Union party, which is part of the ruling coalition.
Truksnis was reportedly hospitalized after the raid but later reported to the headquarters of the anti-graft authority.
Altogether four individuals connected to two different parties were detained on suspicion of illegal party funding.
