Pop legends ABBA are rumoured to be on the verge of reforming and playing some of the slots that Michael Jackson had been scheduled to play before his death.

The Swedish group haven't performed together in over 25 years, but The Sun has claimed that the band have been offered a lucrative deal to reform and take on the mammoth string of dates originally scheduled for Jackson.

David Campbell, chief of AEG Live who organised Jackson's stint at the O2, said: "There's a little foursome out in Sweden we keep talking to."

A source from ABBA, meanwhile, said: ""There are millions on the table. But there are many hurdles to overcome."
