The speculation has come to an end. An anxious day for thousands of <em>Doctor Who</em> fans has ended with the news that Jodie Whittaker will replace Peter Capaldi as Doctor Who. The announcement came in the form of a <em>Doctor Who</em> trailer, broadcast on BBC One soon after Roger Federer became the first man to win Wimbledon eight times. Capaldi will step down after three series and 39 episodes in the role. The <em>Broadchurch </em>star, 35, will make her debut on the sci-fi show this Christmas. Speculation about the identity of the 13th Time Lord had reached fever pitch in anticipation of the announcement, fuelled by the possibility that the new time traveller might turn out be a woman. Phoebe Waller-Bridge, A-list Oscar-winner Tilda Swinton and Olivia Colman, who played Waller-Bridge's mother in the darkly comic Fleabag, all appeared to be in the mix following the finale of the show's 10th series, which ended at the beginning of July, while front-runners for the role included Kris Marshall, the star of the BBC series <em>Death in Paradise</em> as well as Whittaker.
