Labour MP Tom Watson claimed through Twitter that a News Corp source had told him about Rupert Murdoch seeing the draft designs of the Sunday Sun, which is to be launched in April at a discounted price.

There have been expectations about a Sunday edition of Sun, as News Group Newspapers initiated the registration process for The Sun on Sunday and Sun on Sunday trademarks on July 8.

The sunonsunday.co.uk is registered by NI Group Ltd while the domain thesunonsunday.com is registered by News Group newspapers, according to internet domain search site who.is.

The first edition of the Sun on Sunday is going to have pictures rather than story-content, with speculations that the company was planning an April launch.

The circulation of News of the World was said to be around 2.6m copies in 2011, acoording to the Telegraph.
