Michael Jackson fans who bought tickets for his concerts at London's O2 from July will be offered a refund.

Fifty shows - due to start on 13 July and set up as his big comeback dates in the UK - sold out rapidly from official ticket sellers.

Fans who bought directly should now get a full refund, but those who bought from a third party may be out of luck as they have no legal rights.

A statement from official ticket seller Ticketmaster said: "Ticketmaster is aware of the news relating to Michael Jackson. We have no official information at this stage.

"As soon as we have any information we will immediately contact all customers who have booked tickets through Ticketmaster or GET ME IN!"

Ticket exchange business Seatwave.com have announced that it too will refund any tickets bought through its website.

Chief executive Joe Cohen said: "We are all saddened by the news of Michael Jackson's death. All customers who purchased tickets for his O2 shows from Seatwave are covered by our TicketCover guarantee and will get a full refund.

"We advise customers to use the website rather than our phone lines to obtain this information."
