Media group Daily Mail and General Trust has said it will cut around 1,000 jobs at its Northcliffe regional arm this year - double the number estimated last November.
The firm is also making further reductions "across all cost categories" at Associated Newspapers, which owns the Daily Mail and Mail on Sunday.
DMGT said it had seen a "difficult quarter" for its consumer media businesses in the UK and Europe, but expected full-year results in line with market expectations.
Northcliffe has a portfolio of 113 daily, weekly and free newspapers. Titles include the Leicester Mercury, the Bristol Evening Post and the Derby Telegraph.
Despite the full-year reassurance, the firm braced investors for a "substantial fall" in results for the first half of the year due to worsening trading conditions and a change in the timing of its profits.
This will be exacerbated by other factors including the time taken for cost-saving drives to bear fruit, and last month's sale of the Evening Standard.
Advertising revenues remain under pressure across the group. In the quarter to March, Associated's revenues are expected to show a 24% like-for-like decline against a year earlier, with Northcliffe down 37%.
Although classified revenues are "showing signs of stabilisation", job advertising is being hit as unemployment mounts.
"Recruitment revenues are still decreasing and we expect them to be down 55% for the quarter," the company warned.
