Doctor Who fans will finally get a proper tour of the TARDIS in a new episode centred on the time machine.

Journey To The Centre Of The TARDIS is one of the episodes in the forthcoming new series and will reveal much more of the iconic police box than ever before.
Show boss and writer Steven Moffat told the Radio Times: "We've built the rest of the TARDIS!
"The idea is in the title; we're going to journey to the centre of the TARDIS. We've got some great visuals for that."
And guest star Ashley Walters added: "In our episode it'll be the first time people get to see so much of the TARDIS."
Series seven is currently on a "mid-season break" and will return for its remaining eight episodes on 30 March.
