[1] It has been claimed that he first became attracted to the British Union of Fascists (BUF) in 1934 on a trip to London, when he chanced upon a party member delivering a speech and was impressed.

[5] Around then, Hamm converted to the Roman Catholic Church under the influence of Father Clement Russell, a Nazi sympathiser and anti-Semite based in Wembley who kept a photograph of Mosley on display in his parochial house.

[8] After his discharge, Hamm joined and then took over the British League of Ex-Servicemen and Women, which claimed to look after veterans' interests and converted it to a movement designed to keep Mosley's ideas current.

[6] Seeking to keep British fascism alive, Hamm organized a series of meetings in Hyde Park from November 1944 onwards and later moved them to the traditional BUF areas of East London.

Hamm's League rallies eventually began to attract thousands, which convinced him that a proper political return was a distinct possibility.

[10] Hamm's increasing profile did not go unnoticed by both supporters and opponents, and in 1946, he and his ally Victor Burgess suffered a severe beating from antifascists.

[14] Returning to London, Hamm became a central figure in the new anti-black campaign of the UM, which won it some support in Brixton and other areas into which new West Indies immigrants were settling.

[15] He gained widespread press coverage when, in the immediate aftermath of the 1958 Notting Hill race riots, he made a speech outside Latimer Road tube station.

[16] Hamm served as Mosley's personal secretary during the later years of the UM and succeeded to the post upon the death of Alexander Raven Thomson in 1955.
