Haldane refused to join the platform for Asquith's speech at Westminster Central Hall in January 1922. He stated that his main interest in public life was now education reform and that the cause was not best served by endorsing the Liberal Party. It was not until the general election of 1923 that Haldane formally sided with Labour, and made several speeches on behalf of Labour candidates. When the Labour government was formed by Ramsay MacDonald in early 1924, Haldane served once again as Lord Chancellor. He was also joint Leader of the Labour Peers with Lord Parmoor. Haldane was a vital member of the Cabinet as he was one of only three members who had sat in a cabinet before.
