Jodie Whittaker will become the first woman to play the Time Lord in Doctor Who, the BBC has revealed.
The actress, 35, will take over from Peter Capaldi as the 13th reincarnation of the Time Lord.
Capaldi, who first stepped into the Tardis in 2013, will be seen for the last time by viewers in the 2017 Christmas special.
His departure coincides with that of the show's longtime lead writer and executive producer, Steven Moffat, who announced he was quitting in 2016.
Whittaker, who has starred in all three series of Bafta-award winning Broadchurch as Beth Latimer, will team up with the drama's creator Chris Chibnall as he takes over from Moffat as executive producer.
The announcement was made on BBC One following Roger Federer's win over Marin Cilic in the Wimbledon men's final.
The clip, also posted on Twitter by the official Doctor Who account, showed a cloaked Whittaker approaching the Tardis in a leafy forest and opened her hand to reveal a key.
