A coordinating center of the Ukrainian opposition groups, international and local observers who monitored the Sunday parliamentary elections in Donetsk has drawn up a package of documents to be passed to an ad hoc parliamentary commission to investigate irregularities in the elections, UDAR Party parliamentary candidate Valentyn Nalyvaichenko said on Wednesday.

The coordinating center has collected quite a considerable database on numerous electoral districts, at which gross violations were committed during the voting and the vote counting, and "police did not enforce the law," he said.

In particular, Nalyvaichenko insisted on investigating reported vote-rigging at electoral districts 46, 50 and 55 in Donetsk region, where numerous instances of ballot-stuffing were uncovered and recorded, electoral districts 41, 42, 43, 44 and 45, where voters were brought to polling stations in groups, and district 43 where not enough ballot boxes were provided.

Over 1,000 violations were recorded in Donetsk region, which could have significantly affected the voting outcome, Nalyvaichenko said.

UDAR representatives are currently present at vote-counting procedures in district election commissions throughout Ukraine, and "not a single falsifier will escape responsibility," he said.

UDAR also plans to propose amendments to the election laws at a new parliament, taking into account recommendations by the Venice Commission and reports by international observer missions, particularly the OSCE and PACE.
