Ncuti Gatwa regenerated into Billie Piper in the series finale of Doctor Who on Saturday night. He left the role after playing the iconic character for two series. Piper, who previously played the Doctor's assistant, Rose Tyler, said the opportunity to "step back on that Tardis one more time was just something I couldn't refuse".

Following on from the epic season two finale of Doctor Who, viewers were treated to a first look at the next chapter in the Whoniverse, The War Between The Land And The Sea, and new character imagery has been released of Russell Tovey as Barclay and Gugu Mbatha-Raw as Salt.
