The Scotsman and Scotland on Sunday newspapers are to be slimmed down, with a number of pages to be reduced and magazine supplements axed.
It is to lose its weekend magazine, Scotsman Living, and its comment pages are to be downsized to two days a week.
The Saturday issue will have an enhanced arts pullout and a pre-printed TV programme guide to absorb the current magazine content. Scotland on Sunday is also to move to a compact format, necessitating major revamps to its content.
These changes will take effect from 6 January 2014.
