The new VMRO DPMNE leader, Hristijan Mickovski, dubbed Zoran Zaev's Social Democrat-led government a "criminal cartel" at Saturday's rally against Macedonia's current administration.
He accused the government of widespread corruption, a firm grip on the judiciary and media, and of a failure to produce any results for the economy.
Nikola Gruevski, Macedonia's former prime minister and former leader of the VMRO DPMNE party, was jailed for two years on Wednesday for "receiving a reward", in the form of a luxury Mercedes, after previously "illegally influencing" the other two accused to commit the illegal purchase of the vehicle.
The ruling was a first-instance verdict and Gruevski may appeal the sentence.
A Macedonian court has ruled that Prime Minister Zoran Zaev was not guilty of having solicited a bribe of 200,000 euros to help a local businessman buy land in his home town of Strumica.
"I am happy about the acquittal and that I finally proved my innocence and received justice," Zaev said in front of the court after the ruling was issued.
The Office of the Special Public Prosecutor in the Former Yugoslav Republic of Macedonia has opened an investigation into the selection of Greek construction company Aktor as the preferred bidder for the Demir Kapija-Smokvica highway project. Suspects include FYROM's ex-prime minister Nikola Gruevski and former transport minister Mile Janakieski.
Macedonia's SJO on Wednesday said it suspects the leader of the largest ethnic Albanian party in Macedonia, the junior ruling Democratic Union for Integration, DUI, Ali Ahmeti, as well as former Prime Minister Nikola Gruevski, of spending 2.8 million euros on a census in 2011 which they later deliberately scrapped.
Just a few days before Foreign Minister Nikos Kotzias heads to Skopje, a shadow has been cast over negotiations to resolve the name dispute between Greece and the Former Yugoslav Republic of Macedonia after it emerged that his counterpart, Nikola Dimitrov, reportedly described Greece's positions during his contacts with European Union officials as bordering on the "absurd."
