Since the confederation does not have fixed headquarters, the elected Secretary General's local federation becomes the confederation's central operations and a local plenary session of the local federation chooses the secretariats for other leadership positions. Together they are known as the Secretariado Permanente del Comité Confederal (Permanent Secretariat of the Confederal Committee, or SPCC). They, together with other regional federation's secretaries general, form the full Confederal Committee. The first general secretary of the CNT, chosen at its 1910 constitutional congress, was José Negre. He had been secretary general of Solidaridad Obrera, a Catalan union and precursor to the CNT. Thus Barcelona was the first headquarters.
