As General Secretary of the Communist Party, Mikhail Gorbachev authorized the release of thousands of Soviet Jews who wanted to leave the USSR. In 1986 only 914 Soviet Jews were allowed to emigrate; by 1990 the number was 186,815. A group of about 11,000 who had been denied emigration visas were known as refuseniks. Natan Sharansky, a spokesperson for the refuseniks during the mid-1970s, helped draw global attention to their desire to leave and to human rights abuses in the USSR. Arrested on charges of espionage and treason, in 1978 he was sentenced to 13 years of forced labor. His wife Avital led an international campaign to free him. Under pressure from President Ronald Reagan, Gorbachev released Sharansky on February 11, 1986. Sharanksy moved to Israel, where he founded the Yisrael BaAliyah party and later represented the Likud Party, serving as Deputy Prime Minister and Interior Minister of Israel. He continues to be active as the Chair of the Executive of the Jewish Agency for Israel.
