The email read: “The event organisers have been in touch to let us know that, due to scheduling difficulties, they’ve had to postpone The ‘Unbreakable’ Tour at the following venues.” It then lists all the UK venues, before adding that they could not confirm new date at the present time, so full refunds were being given.

In January Jackson cancelled a string of dates in North America after having to undergo emergency surgery. She told fans at the time: “Hey you guys… Happy Holidays to each and every one of you. I need you to know, I learned today, from my doctors that I must have surgery soon.”
