LONDON - The UK's biggest newspaper publisher Trinity Mirror says it expects advertising revenues to be down 10.6% on a like-for-like basis in first half of this year.

The company, which owns around 250 national and regional titles, expects the market to remain "weak" for the rest of 2006.

Its national newspapers - which include The Mirror redtop tabloid - suffered the most, with revenues down 12.1%, while regional titles saw a 9.7% drop.
