After his dismissal from the Defense Ministry post, Sharon remained in successive governments as a minister without portfolio (1983–1984), Minister for Trade and Industry (1984–1990), and Minister of Housing Construction (1990–1992). In the Knesset, he was member of the Foreign Affairs and Defense committee (1990–1992) and Chairman of the committee overseeing Jewish immigration from the Soviet Union. During this period he was a rival to then prime minister Yitzhak Shamir, but failed in various bids to replace him as chairman of Likud. Their rivalry reached a head in February 1990, when Sharon grabbed the microphone from Shamir, who was addressing the Likud central committee, and famously exclaimed: "Who's for wiping out terrorism?" The incident was widely viewed as an apparent coup attempt against Shamir's leadership of the party.
