20 years ago, The Christmas Invasion changed Doctor Who forever

For the first time since 2005, Doctor Who won’t have a Christmas or New Year’s special this year. This comes straight after Russell T Davies’ latest season of the long-running science-fiction drama closed the TARDIS doors on Ncuti Gatwa’s emotionally liberating 15th Doctor and his companion, Belinda Chandra (portrayed to perfection by Varada Sethu). However, the series didn’t end without first revealing the next face of the Doctor’s regeneration cycle: Billie Piper, who previously played Rose Tyler back when Doctor Who returned in 2005.
