Green Shirts' political protest, with ritual marches round the Bank of England, drumming, 'street chalking' and publicity stunts such as throwing a green brick into 11 Downing Street. Initially staying out of parliamentary politics, Hargrave changed his mind in 1935, re-branding the Green Shirt movement as the Social Credit Party of Great Britain and Northern Ireland for the purposes of fighting the 1935 General Election. He was also impressed by the success of the Social Credit Party of Alberta (Canada). Douglas opposed the entry of the movement into parliamentary politics. Hargrave soon travelled to Alberta, frustrated at the lack of progress that the Social Credit government there was making. He was appointed an economic adviser to the Government of Alberta and was disowned by Douglas. He left Canada in 1936, returning to find the Social Credit Party in disarray after the Public Order Act 1936 banned the wearing of uniforms by non-military personnel. Undeterred, Hargrave steered the Social Credit Party into a more evangelical mood, adopting quasi-religious slogans ('God's Providence is Mine Inheritance') and organising public 'Services of National Regeneration'. He broke with Ezra Pound, an episode which underlined his opposition to Fascism. The Social Credit Party was mothballed during the war, although Hargrave tried to keep his ideas alive through a weekly newsletter, The Message from Hargrave. He was urged to stand for Parliament in the 1945 election, but did not: only returning to public politics in 1950 when he stood as a candidate in Hackney North and Stoke Newington in the 1950 general election. The 551 votes he received convinced Hargrave to give up, and by 1951 he had disbanded the Party. Inventor, healer and cartoonist In 1937 Hargrave became obsessed with solving the technological problems of using maps in moving aeroplanes. By 1938 a prototype of the Hargrave Automatic Navigator was ready to file with the Patent Office and articles of association had been prepared for 'Hargrave Aviation Ltd.'. The prototype was tested during the war, with government approval, but lack of capital meant that the invention was not developed further. The invention lay fallow until 1976 when Hargrave sued the British Government, claiming that the moving map display supplied by Britain to the supersonic Concorde, was, in fact, his Automatic Navigator. His claim was taken up by journalists, resulting eventually in a Public Enquiry. Hargrave insisted he was only asking for recognition, rather than any financial
