Newspaper publisher Trinity Mirror has seen a sharp fall in advertising sales and has said the market remains "weak".
The Daily Mirror faces fierce competition from The Sun
The publisher of the Daily Mirror said it expected advertising revenues to be down 10.6% on a like-for-like basis in the 26 weeks to the start of July.
Its national newspapers suffered the most, with revenues down 12.1%, while its regional titles saw a 9.7% drop.
Trinity Mirror said all major advertising categories were weak with the exception of property.
Recruitment advertising across its stable of 240 local and regional titles fell 21% while car adverts fell 13%.
"The advertising environment remains weak and management continue to run the business on the assumption that this will continue for the remainder of the year," the firm said in a statement.
Circulation revenues are expected to be largely flat over the period.
The firm is forecasting a 1.4% drop in sales of its national titles - including the Sunday Mirror and the People - although sales of its regional papers are set to increase by 1.4%.
