Boyle was noted for his extremist views and took an active role in a number of rightist groups in the inter-war period. An
anti-communist by inclination, his views were informed by a landing he made as a Naval Commander in
Vladivostok in 1917 where he claimed to witness examples of
Bolshevik terror that helped to solidify his rightist opinions. He was one of a number of large landowners who joined the
British Fascists in the early 1920s, largely inspired by slump in agriculture and the simultaneous rise in taxation that they blamed on
democracy and the rise of the left. Boyle served as leader of the British Fascists units in Scotland. Close to Brigadier
R. B. D. Blakeney, Boyle joined Blakeney's splinter group the Loyalists in 1926 in order to support the work of the
Organisation for the Maintenance of Supplies. This group had agreed to disavow
fascism in order to co-operate with the government. Boyle disappeared from the political scene soon afterwards when, virtually bankrupted by the burden of his large estates, he emigrated to
France, remaining there until 1930. Following his return to the United Kingdom, Boyle once again became involved in rightist politics and was a regular invitee to the
January Club, a high society discussion club organised by the
British Union of Fascists. According to contemporary
Labour Party documents Boyle subsequently provided funding to
Oswald Mosley's party, which was one of the intentions of the January Club. Boyle also joined the
Anglo-German Fellowship. ==Peerage==
