Former Doctor Who star Peter Davison's daughter Georgia Moffett is reportedly in the running to play the Time Lord's new companion.

Moffet's casting for a key part in the upcoming fourth season was announced in December, but the Daily Star claims that she may become a regular in the Tardis for the fifth season in 2010

However, according to the report she will have to fend off a challenge from 23-year-old actress Felicity Jones for the coveted companion role. Jones, who will also feature in the next season of Doctor Who in an episode revolving around Agatha Christie, is best known for her parts in The Worst Witch and Cape Wrath, alongside her role as Emma Grundy in long-running radio soap The Archers.

"Several names are in the frame," a source told the tabloid, "but Georgia and Felicity are currently on top of the shortlist - both have their merits."
