Strictly Come Dancing has been the subject of headlines in recent months following allegations about the behaviour of two of the show's professional dancers.
Giovanni Pernice has faced allegations about his teaching methods, which he denies, while Graziano Di Prima has faced allegations about his conduct with a past participant.
In response to what the BBC has called "concerns" that are "fundamentally about training and rehearsals", the corporation announced new welfare measures, including the introduction of a production team member who will be present "at all times" during training room rehearsals.
