One of the most successful BBC TV shows, Strictly Come Dancing, is back on air for its 20th year after it was rocked by a summer of in-house scandals. An investigation into harmful work practices was launched by the BBC when two of Strictly's two professional dancers, Italians Giovanni Pernice and Graziano Di Prima, were accused of bullying and inappropriate behaviour during rehearsal sessions. Both men denied the accusations, but pressure mounted on the BBC to take action after other former celebrity contestants shared their concerns over treatment they received while they competed. So what does this latest scandal at the BBC mean for British TV in general and can Strictly come back from this one? Chatting to The Explainer today are Hannah Hope and Alex Doyle of The Sun UK's Showbiz section.
