Murdoch had led the print unions to think that the Wapping plant was to be used for a new evening newspaper, the "London Post". This began what became known as the Wapping dispute. In support of sacked members, the print unions organized regular demonstrations outside the company's premises in Pennington Street, with six pickets posted on Virginia Street and marches of large numbers of people usually converging nearby on The Highway in Wapping. The unions and leading members of the Labour Party also called for a boycott of the four newspapers involved.
