The BBC has been attacked for casting a white actor in a role originally written for a black one in a new thriller.
Danny Lee Wynter, who set up diversity campaign Act for Change, said black actors were "confused and understandably angry" when Edward Holcroft was chosen for London Spy after many of them had auditioned.
He said the part was originally advertised for "an immensely talented non-Caucasian actor" and auditions had taken place for what was described as "a pivotal role in this brilliant original drama series".
He claims some black actors had been "in serious talks".
Mr Wynter, 32, said: "To change the race of a character seems a cavalier decision to make, especially so very late in the casting process.
