'GEC Plessey Telecommunications' ( 'GPT'), was founded in 1988 as a telecom joint venture between 'GEC' and the historic British electronics, defence and telecommunications company - 'Plessey'. A joint holding company of GEC and German conglomerate - Siemens AG acquired Plessey a year later, and GPT was converted into a '60/40 GEC/Siemens joint venture'.
