Socialist Party of Great Britain



Socialist Party of Great Britain



The Socialist Party of Great Britain (SPGB) was formed in 1904 as a breakaway from the Social Democratic Federation, the first organisation to propagate Marxist ideas in Britain.

The Marxism of the SPGB is a continuation of that of the extreme leftwing of pre-WWI Social Democracy, rejecting all Leninist accretions (vanguard party, Bolshevik seizure of power as proletarian or socialist revolution, distinction between socialist society and communist society, theory of aristocracy of labour maintained out of superprofits of imperialism, transitional demands). The SPGB pioneered the view in Britain that Russia was neither a “workers state” nor socialist, but state capitalist. It advocates no minimum programme of reforms to be achieved within capitalism, but only socialism. It endorses trade union action on sound lines.
