A four-part referendum was held in Russia on 25 April 1993. Voters were asked questions on confidence in President Boris Yeltsin, support for the government's socio-economic policies and early elections for both the presidency and parliament. The referendum was initiated by the Congress of People's Deputies, which stipulated that Yeltsin would need to obtain 50% of the electorate, rather than 50% of valid votes. However, the Constitutional Court ruled that the president required only a simple majority on two issues: confidence in him, and economic and social policy; though he would still need the support of more than half the electorate in order to call new parliamentary and presidential elections.
