In 1981, a group of Labour moderates left their party to form the Social Democratic Party. They were joined by the former Labour deputy leader, Chancellor and Home Secretary Roy Jenkins, who had previously had discussions with Steel about joining the Liberals. Under Jenkins' leadership, the SDP joined the Liberals in the SDP–Liberal Alliance. In its early days, the Alliance showed so much promise that for a time it looked like the Liberals would be part of a government for the first time since 1945. Opinion polls were showing Alliance support as high as 50% by late 1981. Steel was so confident that he felt able to tell delegates at the Liberal Assembly that year, "Go back to your constituencies, and prepare for government!"
