The following year, a group around the leadership of the BSP formed the new National Socialist Party, which attracted some Defence Committee members.
Fisher instead refounded Defence Committee as the British Workers League, which at its peak included fifteen Labour Party Members of Parliament.
[2] Fisher worked with George Nicoll Barnes to reconstitute the British Workers' League as the National Democratic and Labour Party (NDP), and stood candidates at the 1918 general election.
He received substantial secret funding through Viscount Milner and worked closely with the Unionist Chamberlain family in Birmingham.
He then withdrew from formal politics, but subsequently led a variety of organisations, including the Society for the Study of Religions, Anglo-French Alliance, and National Organization of Ratepayers.
