The Radio Times is producing a special Jubilee issue that will have four separate covers for the same edition of the magazine, which the BBC hopes will prompt buyers to collect all four. The issue contains a full guide to broadcasting over the Queen's Golden Jubilee weekend, plus a look back at her 50-year reign. The issue, dated June 1-7, goes on sale Tuesday, May 28, and will be distributed by Frontline. {{CTN }}
