The BBC has revealed that Jemma Redgrave will return for another two episodes in the new season of Doctor Who.

In addition to her return in Season 9’s opening two-parter, a new video on the show’s official website confirms that Redgrave will be back again as Kate Stewart in Episode 7 and Episode 8.

The writer(s) of the two episodes – which may just be “linked”, rather than a two-parter – have not yet been announced, but it seems likely that UNIT will be involved in the story.

Redgrave told the BBC: “I’m here for the readthrough of Episode 7 and 8. I’m here in Cardiff and really, really happy and thrilled because Kate Stewart is back.”

Filming of the two episodes is expected to begin shortly.

The actress has played UNIT’s Chief Scientific Officer – the daughter of classic character Alistair Gordon Lethbridge-Stewart – since 2012 in ‘The Power of Three’, ‘The Day of the Doctor’ and ‘Death in Heaven’.

It was revealed yesterday that the new season will apparently consist of 12 episodes, followed by a Christmas special.

Season 9 began filming in Cardiff in January and will air on BBC One this autumn.
