The London insurance market along with millions of Kylie Minogue fans are suffering a nervous few weeks following the announcement that the Australian pop queen has breast cancer.

The singer announced she would have to cancel up to 20 shows in Australia as she undergoes immediate treatment for her condition.

Insurance Times has learned that the tour event cancellation cover is placed in the London market. Claims for the cancellation of the tour dates could top £1m.

But sources in the UK said the dates could be rearranged depending on the outcome of her treatment. "It is a massive production. These shows involve hundreds of production and performance staff.
