Trinity Mirror’s regional titles will not be affected by the group’s recent cost-cutting exercise although the Scottish editions of The Mirror and The Sunday Mirror will cease to publish.

The newspaper group, publisher of the Daily Mirror, Sunday Mirror and The People, has unveiled plans to implement a £3m web-based content management system and create a multimedia newsroom, at the expense of 200 editorial jobs.

The newspaper group currently employs 550 editorial staff, and aims to cut 140 full time editorial jobs and 60 part-time staff across its publications.

Changes will include outsourcing sub-editing, merging news and features, and combining print and web teams.

These moves are the latest in a long line of cost-cutting exercises by Trinity Mirror, which has closed a host of local newspapers and drastically reduced its staff numbers to help tackle a tough newspaper market.

However a spokesperson for Mirror Group has said that the editionising of The Mirror and Sunday Mirror in Scotland would also be coming to an end.

Richard Wallace (pictured), editor of the Daily Mirror, explained: “Our future is a multimedia one and we need to transform ourselves into an agile media business, ready to grasp the opportunities and challenges of the multimedia world we now inhabit.”

The group has now entered a 90-day consultation with staff likely to be affected. It has also launched a voluntary redundancy scheme.

Meanwhile, GMG, publisher of The Guardian and The Observer, has lost £171m in the past year.

The losses, which were 77% worse than the previous year, have mainly been down to a £96.5m writedown on the group’s investment in Emap and a £63.9m impairment charge on GMG radio.

£47m was also written off after the group sold its media division to Trinity Mirror in February, bringing total losses to £207.4.
