The Observer plans monthly music title with ads by Mother

The Observer is launching a further magazine supplement, the Observer Music Monthly, later this year.

The 68-page magazine is the third magazine supplement to be launched by The Observer, and follows the existing Observer Sport Monthly and Observer Food Monthly magazines.

The Observer has not confirmed a launch date but Mother has been enlisted to create an ad campaign for the launch.

Caspar Llewellyn Smith, the assistant editor of The Telegraph Magazine and a former editor of The Daily Telegraph's Saturday Arts and Books section, is joining The Observer to edit OMM.

He said: "The magazine will provide a great opportunity to review the way music is covered in the print media."
