The fresh magazine, Action, launches in June and replaces Common Cause, the charity's previous supporter publication. An online version will launch in October.
Action has been designed by ethical communications agency Neo to appeal to a younger generation of supporters. It will have a glossier look and has been reduced in size from A4 oversize to A4 as a cost-cutting measure.
Following the success of Slumdog Millionaire, the first issue will examine the reality faced by children living in the urban slums of India.
Action will initially go out to 180,000 supporters, with the number set to increase for further issues. As its predecessor, the magazine will be published three times a year, in February, June and October.
