LONDON: The UK's biggest newspaper publisher, Trinity Mirror Group, expects the decline in advertising revenue to slow later this year, despite a 2.4% slide in the first four months - evidence of current "volatile and challenging conditions".

The company, which owns over 250 regional and national titles, said ad income for the regional division fell 2.3%, while national advertising revenues fell 4%.

Among its several national titles, TMG owns daily tabloid The Mirror and its sibling Sunday Mirror. Group circulation revenues fell by half a percent in the same period.

The automotive advertising category showed the steepest slide of 11.4%, according to the company. Display advertising slipped 1.2%, while recruitment was down 3%. Other categories fell 4.3%, but property ad revenues increased 4.1%.

Fortunes were better on the digital front, where regional revenues rose 24.8%, and the national division reported a 30.7% increase, boosted by the relaunch of the The Mirror's website. But digital still accounts for just 3% to 4% of total income.

The publisher announced in December the sale of some of its regional titles and the Racing Post, from which it expects to reap around £600 million ($1.18bn; €880m).
