As veteran broadcaster and journalist Michael Ryan retires, it has been announced that Anne Cassin is to co-present Nationwide with Mary Kennedy.

A newscaster with RTÉ since 1998, Cassin was most recently seen presenting the All Island School Choir Competition and has presented Capital D for a number of seasons.

Capital D will not be part of the 2012 schedule.

Nationwide is seen by an average audience of almost 350,000 people every Monday, Wednesday and Friday at 7:00pm on RTÉ One.

Michael Ryan's last Nationwide broadcast is on RTÉ One on Friday December 23 at 7:00pm.

The Capital D Christmas Special is on at 7:00pm on Thursday December 22 on RTÉ One and features Crosscare's St Brigid's Food Centre, the East Wall Butcher's Christmas grotto, Eamon Coghlan's favourite Dublin places and this season's Christmas jumpers.
