Further journalism redundancies have been announced on the Mirror titles because digital advertising growth is failing to offset print decline.
The move comes despite the fact that digital audience growth appears to be exceeding print circulation decline.
Trinity Mirror group editor in chief Lloyd Embley warned that six further editorial jobs are to go.
He said: “As you are aware, our industry – and our company – is continuing to face financial pressure.
“We are showing strong growth in digital advertising revenues but, at the moment, this can’t offset the significant decline in print.
“Consequently, we have had to take another look at our cost base and make some exceedingly difficult decisions.
“As always, we have taken as much as we can from areas which don’t impact on jobs.
“However, it has not been possible to avoid this completely so we are, unfortunately, proposing a small number of redundancies.
“Across editorial and editorial support the proposal is a reduction of six roles.
“Everyone involved has already been contacted and we have entered a consultation period.
“Thank you all in advance for your understanding during another extremely challenging and upsetting process.”
