As reported by a parliamentary correspondent for Censor.NET, the online chat between the lawmakers was captured on camera during Thursday session of the Verkhovna Rada.
"Hurray! We'd be much better now!!!)))" Heller wrote to Voropaiev.
"Tell me how much better," Voropaiev replied.
"Okay!!! We'll definitely do better now," Akhmetov's business partner Heller expressed confidence.
"DTEK's bonds are up even more today. You are making fortune faster than Petro Oleksiiovych [Poroshenko - ed.]. It's not very nice," Voropaiev wrote.
Heller is known as a long-time business partner of Rinat Akhmetov. Voropaiev is unofficially considered Akhmetov's counsel.
According to Forbes, Rinat Akhmetov remains the richest Ukrainian with his fortune having doubled from $2.3 to $4.6 billion last year.
