Independent parliamentarian of Ukraine Serhiy Leshchenko will be summoned to the General Prosecutor's Office, and then he will probably be handed a suspicion notice, said Prosecutor General Yuriy Lutsenko.

"Our investigation into the Burisma case is independent, non-politicized and impartial ... MP Leshchenko will be summoned by investigators, he will be asked questions and probably handed a suspicion notice on disclosing pretrial investigation data on the so-called "black ledger" of the Party of Regions, which led to interference with the U.S. election from the territory of Ukraine," Lutsenko told Ukrainian TV channels on Tuesday.
