From June 1975 to March 1976, Sharon was a special aide to Prime Minister Yitzhak Rabin. He planned his return to politics for the 1977 elections; first, he tried to return to the Likud and replace Menachem Begin at the head of the party. He suggested to Simha Erlich, who headed the Liberal Party bloc in the Likud, that he was more able than Begin to win an election victory; he was rejected, however. He then tried to join the Labor Party and the centrist Democratic Movement for Change, but was rejected by those parties too. Only then did he form his own list, Shlomtzion, which won two Knesset seats in the subsequent elections. Immediately after the elections, he merged Shlomtzion with the Likud and became Minister of Agriculture.
