Many of the problems that Aden had suffered in its time as a colony did not improve as a federated state. In the new federation the Aden Trade Union Congress (ATUC) had a large influence in the new assembly and to prevent it seizing control of the federation in 1962 the former Colony of Aden had joined the Federation of South Arabia so that Aden's pro-British assembly members could counter the ATUC's influence.[3]
