London's new Sunday newspaper may be a close cousin of the London Sunday newspaper that's folding this week..

The announcement Thursday that the News of the World, Rupert Murdoch's Sunday-only U.K. tabloid, would publish its final edition this weekend has sparked rumors that The Sun, another Murdoch-owned British newspaper, would start publishing on Sundays in its place. The Sun currently runs Monday-Saturday.

The registration of the online domain name TheSunOnSunday.co.uk Tuesday, two days before News of the World's collapse was announced, appears to prove the rumors correct.

News of the World's shuttering came while the newspaper was mired in a phone hacking scandal that sparked a police investigation and prompted advertisers to abandon the newspaper and a prominent veterans group to cut off ties with it.
