In the
1962 election, Social Credit won 26 seats in Québec, led by Caouette, who returned as the member for Villeneuve. He held this seat until 1968, when he transferred to the newly created
Témiscamingue, a riding he would hold for the rest of his life. The party won only four seats in the rest of Canada. Under the circumstances, Thompson, now the MP for
Red Deer, was all but forced to name Caouette as the party's deputy leader. Holding the balance of power in the
House of Commons of Canada, Social Credit helped bring down the
Progressive Conservative minority government of
John Diefenbaker. However, in the
1963 election, Social Credit was reduced to 24 seats nationwide, all but four of which were in Quebec. Caouette fought for
bilingualism in the House of Commons, winning a symbolic victory when he got the Parliament's restaurant to produce bilingual menus. In this, he anticipated the
official bilingualism policy that
Pierre Trudeau's government would later enact. The Socred MPs from Québec considered Caouette as their true leader. Over time, Caouette came to believe that since the party was most successful in Québec, he should be the leader of the party instead of Thompson. As well, Caouette and his followers remained true believers in the social credit monetary theories of
C. H. Douglas while Thompson and the party's two most powerful branches—in
Alberta and
British Columbia—had largely abandoned the theory. Thompson refused to step aside, prompting Caouette and virtually all of the Socred MPs from Quebec to split from the party in 1963 and establish the
Ralliement des créditistes as a separate political party. In the
1965 election, Caouette's
Ralliement won nine seats, while Social Credit led by Thompson won five seats. In the
1968 election, Caouette's party won 14 seats while Social Credit won none. The two parties were reunited under Caouette's leadership for the
1972 election. The reunited Socreds won 15 seats in that election, all in Québec. It would never elect another MP from English Canada, though it continued to nominate candidates outside of Québec. ==Later political career==
