Ncuti Gatwa has left Doctor Who and said he “loved every minute of it” as he is seen regenerating into Billie Piper in the season finale.

Piper, 42, first appeared in the series as the companion to the ninth Doctor in 2005, playing Rose Tyler alongside Christopher Eccleston’s Time Lord – and then again for the 10th Doctor played by David Tennant.
