Answer the following question: Extract the answer to the question from the following context. Question: what leader is mentioned first? Context: Gorbachev also radically expanded the scope of Glasnost, stating that no subject was off-limits for open discussion in the media. Even so, the cautious Soviet intelligentsia took almost a year to begin pushing the boundaries to see if he meant what he said. For the first time, the Communist Party leader had appealed over the heads of Central Committee members for the people's support in exchange for expansion of liberties. The tactic proved successful: Within two years political reform could no longer be sidetracked by Party "conservatives." An unintended consequence was that having saved reform, Gorbachev's move ultimately killed the very system it was designed to save.
Answer:
Gorbachev
