London's weekly Observer will roll out its long-awaited redesign and conversion to the Berliner format on Jan. 8, it was announced today.

The new-look Observer will include a full-colour news section and a new, separate listings section to sit alongside the Observer magazine.

"Sundays have changed dramatically over recent years and the Berliner Observer will be the most modern, punchy, engaging Sunday paper, with more variety for the reader, more interactivity with our audience, fantastic use of pictures, a brilliant stable of writers, and the best array of magazines in the market," said the editor, Roger Alton.

The Observer's daily sister paper, The Guardian, relaunched as a Berliner to much fanfare in September. The Guardian's circulation spiked from 340,000 in August to 408,000, but fell to 401,000 in November, prompting some commentators to question whether the £100 million relaunch was wise.
