ドイツ社会主義労働者党
This position was contested by Andrés Nin and some other members of the League who did not support the call for a new International. This group prioritised regroupment with other communist oppositions, principally the International Communist Opposition (ICO), linked to the Right Opposition in the Soviet Party, a regroupment which eventually led to the formation of the International Bureau for Revolutionary Socialist Unity. Trotsky considered those organisations to be centrist. Despite Trotsky, the Spanish section merged with the Spanish section of ICO, forming the Workers' Party of Marxist Unification (POUM). Trotsky claimed the merger was to be a capitulation to centrism. The Socialist Workers' Party of Germany, a left split from the Social Democratic Party of Germany founded in 1931, co-operated with the International Left Opposition briefly in 1933 but soon abandoned the call for a new International.
