John and Peggy Loder travelled on a world tour in 1924, including a visit to Australia. Although initially unimpressed, describing Sydney as "afflicted with so much Victorian architecture of the worst kind", by the end he had warmed to the country, writing that Australia was "a splendid country with splendid people" possessing a "democratic spirit". Returning to England, Loder was narrowly elected as the Conservative Member of Parliament for Leicester East in 1924, a seat he held until being defeated in the 1929 General Election. Loder then made several visits to Bolshevik Russia, writing another book entitled: "Bolshevism in Perspective" (1931). In 1931 he returned to the House of Commons as member for Lewes, and represented this constituency until succeeding his father on his death as the second Baron Wakehurst in 1936, who had been raised to peerage in 1934. Loder then entered the House of Lords.
