The National Union of Printing, Bookbinding and Paper Workers became the Society of Graphical and Allied Trades Division A and NATSOPA became the Society of Graphical and Allied Trades Division 1.
The aim was to achieve a complete merger over time, but differences led to in-fighting and in 1970 the two divisions split, Division A retaining the name Society of Graphical and Allied Trades and Division 1 becoming the National Society of Operative Printers, Graphical and Media Personnel (but retaining the NATSOPA acronym).
The union did not initially sponsor Parliamentary candidates, but shortly after the 1979 general election, it changed its policy.
It sponsored Bob Litherland's successful candidacy in the 1979 Manchester Central by-election, and also began sponsoring Ron Leighton, who was already a sitting Member of Parliament.
