Ukrainian Prosecutor-General Yuriy Lutsenko says the so-called “black ledgers” of the Party of the Regions – accounting papers where the amounts of money paid by the disgraced Ukrainian ex-president Viktor Yanukovych for various services – had no signature by the party’s U.S. political consultant Paul Manafort that would confirm the actual receipt of money and therefore cannot serve as a sole evidence of him receiving such payments from Ukrainian politicians.
