DOCTOR Who will be reunited with ex-sidekick Martha Jones yet again, TV Biz can reveal.

Bosses are lining up Freema Agyeman to make a surprise return in one of this year’s four specials marking David Tennant’s last hurrah as the Timelord.

The move has surprised fans as Freema, 29, reportedly annoyed Who chiefs after she signed up for ITV1’s Law and Order: London.

Show creator Russell T Davies was then forced to tear up scripts for Who spin-off Torchwood, in which she’d been given a starring role.

But sources confirmed the Londoner will reprise Martha for the BBC1 hit later this year. An insider said: “Freema’s on board. It’s early days so it’s unclear what exactly Martha will be up to in the new show.

“Whatever happens it’s good news for Freema and shows that whatever friction there was between her and Who bosses has gone.”

Freema has a chequered history with Doctor Who after signing up in the third series, replacing Billie Piper, 26.

She only lasted one series before she was replaced as 37-year-old Tennant’s sidekick by Catherine Tate, 40.

However bosses still featured guest appearances by Martha in four episodes of the last series, as well as putting her in the second Torchwood series.
