Doctor Who's new sidekick revealed

LONDON - The BBC has unveiled Doctor Who's new sidekick to replace Billie Piper's Rose Tyler.

Freema Agyeman, 27, will take over the role as the time-travelling adventurer's companion in the third series of the re-launched TV drama.

"Billie rightfully built up an amazing fan base and she will be missed, but I hope the fans are willing to go on new adventures with me," she said.

Agyeman has already appeared on the show as character Adeola who suffered at the hands of the cybermen in the episode aired last Saturday.

The programme's writer Russell Davies said her performance had impressed enough to call her back for an audition with David Tennant who plays the Doctor.

"It was an immediate and sensational combination, and her range, presence and charm blew us all away."

Piper bows out at the end of the current series after two years in the role during which her screen career has blossomed.

Agyeman will join as new character Martha Jones but will not feature in this year's Christmas special.

"We've got another surprise in store for that," Davies said.
