If there was a Bafta award for Most Woke Television Drama, a BBC production would win every year hands down. Consider some of 2020’s highlights alone: Noughts and Crosses, set in an alternate world where the ruling class is black and in which white people are the victims of racism; My Name is Leon, about a mixed-race boy growing up in care; and A Suitable Boy, a drama about arranged marriages with an entirely Indian cast.
