b) Closing NoTW is a cynical move that doesn't hurt News International at all
It actually benefits NI. NotW was an expensive operation (all those fake sheikhs, phone taps and bin rummaging doesn't come cheap) with a separate newsroom. Closing that down and producing a 7 day Sun filled with long-lens shots of various microslebs and reality TV articles from the Sun's existing newsroom will save them several tens of millions a year.
The markets will love it, and Rebekah Brooks will get a bit smoochy kiss from Uncle Rupert.
