Solovjov, 68, has said he intends to retire.
According to the Commercial Register, Solovjov has been a member of the Center Party since 2003.
The verdict handed to Solovjov and former Kohtla-Jarve deputy mayor Juri Kollo in October 2015 became final on Monday when the Supreme Court decided not to handle the men's appeal.
The Viru county court on Oct. 28, 2015 found Solovjov and Kollo guilty of corruption crimes. The court found Solovjov guilty of embezzlement, competition related offenses and offenses related to breach of the duty to maintain integrity, counterfeiting and using counterfeit documents, and misuse of trust. The court handed him a conditional jail sentence of five years with a probation period of five years.
According to the indictment, the board member of a company that provided services to the city of Kohtla-Jarve presented to the city government false information from September 2006 to August 2009 about maintenance, service and cleaning works performed. The reports were accepted by the city government for the payment of invoices. Besides acceptance and survey records concerning the works were falsified retroactively along with the budget presented by the company to the city government to conceal the unlawfulness of the payments in excess of the budgeted amount.
In 2009 the Kohtla-Jarve city government conducted tenders to find companies to perform various works and services, in the course of which the mayor allegedly misused his official position by creating favorable terms for entrepreneurs he knew, including to two companies.
With a population of more than 37,000, overwhelmingly Russian-speaking Kohtla-Jarve is the fifth biggest city of Estonia.
