In May 2015, protests occurred in Skopje against Gruevski and his government. The demonstrations began following charges being brought against Zoran Zaev, the opposition leader, who responded by alleging that Gruevski had had 20,000 Macedonian officials and other figures wiretapped, and had covered up the murder of a young man by a police officer in 2011. A major protest occurred on 5 May, with violent clashes between activists and police, causing injuries on both sides. In the days following, the opposition claimed that more anti-government actions would occur, which they did later that month. Several ministers, including the interior minister, resigned. Gruevski initially refused to step down, saying on 16 May that "if I back down it would be a cowardly move ... I’ll face down the attacks." However, on 15 January 2016, Emil Dimitriev was nominated as Prime Minister and he assumed office on 18 January, following the arranged pre-electoral resignation of Gruevski from the position, as part of the Przino Agreement.
