The jail time for Liviu Dragnea, party leader of the ruling Social Democrats, came after a conviction last year for having two party members paid by a public agency for fake jobs.
According to prosecutors, Dragnea intervened from 2008 to 2010, when he was a government official, to keep two women employed by his party on the payroll of the family welfare agency. The women admitted working for the party while they received salaries from the public agency.
Dragnea, already blocked from being Romania's prime minister because of a 2016 conviction for vote-rigging, was expected to be imprisoned within 24 hours.
Dan Barna, chairman of the opposition Save Romania Union party, welcomed the court ruling, which had been delayed for months after Dragnea appealed the June 2018 conviction.
"Today's ruling ends the Dragnea era, one of the darkest over the last 30 years," Barna said in a Facebook post. "Romania is getting healthier, we are coming back to Europe."
Dragnea's party suffered huge losses in European Parliament election on Sunday, falling to second place behind the opposition National Liberal Party.
Additionally, a non-binding referendum called by President Klaus Iohannis, a government opponent, seeking to pressure the government into stopping its efforts to water down anti-corruption measures won support from 80% of voters on Sunday.
