Threatened strikes by railwaymen's union (predominantly Menshevik) and post and telegraph union if Bolsheviks didn't hold talks with other parties
Lenin opposed power sharing, threatened moderates with Red sailors from Kronstadt for forceful Bolshevik control -moderates, including Kamanev, Zinoviev, Rykov, and Milyutin resigned from the Central Executive Committee when the Committee voted for Lenin's proposal to suppress all bourgeois newspapers (smacked of the beginnings of dictatorship).
Party split
1. Left SRs supported Lenin on 25 Oct
2. Left SRs more radical, aligned with Bolsheviks in late 1917
