Tryouts for the talent show in Manchester, England were delayed by two days last week (ends12Jul15) as music mogul Cowell mourned the death of Julie, who passed away on 05 July (15).

The next round of auditions was due to take place at The SSE Arena in north London on Tuesday (14Jul15) but the sessions have been cancelled due to "unforeseen circumstances", according to a spokesperson for the show.

The news has led to speculation Cowell's mother's funeral will take place on Tuesday.

The auditions are set to resume on Wednesday (15Jul15).
