“I’m not aware of anywhere else where we’ve seen such a brazen and open attempt to corrupt an election,” Moldova’s chief anti-corruption prosecutor, Veronica Dragalin, told me this week in her office in Chisinau.

Born in Moldova, she spent most of her life in the US – most recently as a prosecutor in Los Angeles – before returning to the country and a job in a small office on the fifth floor of a Soviet-era block with a broken lift.

What her team say they have uncovered, working with police, is a pyramid payments scheme openly run from Russia by Ilan Shor and his group.

“We’re talking about a foreign country sending money in an attempt to influence the election,” Ms Dragalin spells it out. She details evidence gained through wiretaps, police infiltrators and witnesses – some of which her office has made public.

“At the start they tried to make it look legitimate. Now it’s almost like they’re flagrantly flaunting all the laws… [and] openly influencing the decision to vote,” the prosecutor says.

“The primary goal is to have the referendum fail.”

According to her team, once the cash couriers were detected at the airport and that route made more difficult, payments began to be channelled via a sanctioned Russian bank, PSB.

By early October as many as 130,000 voters had received payment through this scheme – about 10% of the active electorate, according to Viorel Cernauteanu, the chief of police.

“In September alone, $15m (£12m) was transferred,” he told me, explaining how they could trace funds and recipients because they gave personal data to open a bank account.

Offering money or goods in return for votes is a crime with a possible five-year jail sentence. Last month, a new law made it an administrative offence to accept money, too.

But in one of Europe’s poorest countries it is not hard to find willing recipients of cash.
