Speculation is reigniting over the launch of the Sunday Sun by News Corp boss Rupert Murdoch, which will replace the defunct News of the World (NotW), after reports it will hit news stands on 29 April.

According to Journalism.co.uk, unnamed News International sources have confirmed to them that this will be the launch date.

New International is refusing to confirm or deny the rumours and there has been no public acknowledgment that plans for a new publication even exist.

Tom Watson, a Labour MP who sits on the media select committee that grilled Murdoch over phone hacking at NotW, fuelled speculation about Murdoch's next Sunday tabloid on 23 January.

"A News Corp source tells me Rupert Murdoch has seen the draft designs of the Sunday Sun with a launch in April at a discounted price," Watson tweeted.

It's thought former NotW staff will have roles in the new publication.

NotW, a profitable newspaper, was closed by Murdoch in July 2011 after revelations about phone hacking at the newspaper.

It emerged that NotW journalists had hacked the phone of murdered schoolgirl Milly Dowler while she was missing, as well as 7/7 terror attack victims' relatives and a host of celebrities.
