Billie Piper to return to Dr Who

Piper first joined when the Doctor was Christopher Ecclestone

Actress Billie Piper is to return to Doctor Who, the BBC has confirmed.

She will star in three episodes of the sci-fi drama, reprising her role as the Doctor's companion, Rose Tyler.

Rose's return will mean the Doctor has three assistants in next year's series - Donna, played by Catherine Tate, and Freema Agyeman as Martha.

The new series begins in March and will run for 13 episodes. There will be three special editions in 2009 before the show takes a break until 2010.

Piper left Doctor Who last year, when she was transported into a parallel universe.

Awards

Her character had proven a hit and the star won a number of awards for her performances. She was named most popular actress at the National Television Awards in 2005 and 2006.

A separate show based on Rose had been planned by writer and series producer Russell T Davies, but was scrapped when Davies decided the programme was "a spin-off too far".

Filming is currently under way in Cardiff for the new series of Doctor Who, which sees the Doctor meeting an old group of enemies - the Sontarans - 35 years after first encountering them.

Before that, the programme will return to television screens at Christmas with a special episode set on the Titanic, which will co-star singer and actress Kylie Minogue.
