Strictly Come Dancing star John Whaite has been forced to pull out of Sunday night's tour performance of the live dancing show. John, 32, has tested positive for Covid-19 on a later flow test and, despite feeling "fine", he must await the results of a PCR in isolation to determine his fate. Great British Bake Off star John, who is paired with Johannes Radebe on the tour, explained his situation to fans in a video posted to his Instagram story on Sunday.
