Rihanna cancels Sunderland and Cardiff tour dates

Rihanna has cancelled some dates of her UK stadium tour. 

So far, Sunderland's Stadium of Light and Cardiff's Principality Stadium both been pulled from the Anti tour.
But her Coventry date at Ricoh Arena will still go ahead although it has been rescheduled from 14 June to 25 June.
It's all down to "logistical reasons beyond the tours control" according to a statement and refunds will be available.
