Macedonia's opposition leader has published what he says is new evidence of government vote-manipulation in three recent elections, following up on accusations of a massive wire-tapping scandal.

Social Democrat leader Zoran Zaev released what he said were recorded conversations between conservative government officials and Macedonia's intelligence chief.

Addressing more than 2,000 party supporters Tuesday, Zaev claimed the officials discussed vote-buying and intimidation ahead of 2011 and 2014 parliamentary elections, and 2013 local elections.

The alleged plans included incapacitating elevators at polling centers in opposition-dominated constituencies.

Zaev demanded Prime Minister Nikola Gruevski's resignation, claiming he was behind the alleged illegal wiretapping of more than 20,000 people, including politicians, judges, journalists, police, religious leaders and foreign ambassadors.

Gruevski denies wrongdoing, claiming the recordings were fabricated with the help of foreign spies.
