 Around 5,000 members, led by John Aitkin, decided to split away in order to remain within the mainstream trade union movement, and founded the Electrical and Plumbing Industries Union.The union merged with the Amalgamated Engineering Union to become the Amalgamated Engineering and Electrical Union (AEEU) in May 1992, so the electricians were now part of the TUC.The AEEU was led by Ken Jackson, who belonged to the EETPU.
