In 1923 he was re-elected to parliament with an increased majority; In 1924 at the General election, the Labour party chose to field a candidate against him with disastrous effects, causing his defeat; In 1929 he re-gained his Birkenhead East seat and returned to parliament after an absence of five years; In 1930 he served a second term as a Member of the Executive Committee, of the League of Nations Union.

In 1931 at the General Election, the Conservatives chose not to field a candidate against him as the parties were partners in the National Government, as a result, White was comfortably re-elected; In 1932 he resigned from National Government office along with all the other Liberal party Ministers who followed Sir Herbert Samuel.

There were calls for the Liberal and Labour parties to join together in a Popular Front to defeat the National Government.

By the autumn of 1939, the Birkenhead Labour party had no candidate in the field[16] and a straight fight with a Conservative was anticipated.

In 1940 he was elected a Member of the Executive Committee of the British Council, a body specialising in international educational and cultural exchange.
