Rumours emerged at the start of the year that Guardian Media Group (GMG), which publishes The G uardian and its Sunday sister paper The Observer, was considering outsourcing its printing, but that it would be Rupert Murdoch's News UK that would take on the work, a move that would have caused an editorial clash with the Guardian 's left-leaning outlook. Instead it appears that Trinity Mirror, which publishes the Daily Mirror along with numerous regional titles, will take on the work. The Telegraph reported that Trinity won the work ahead of News UK and also Johnston Press, which prints The Guardian in Northern Ireland.
