They’re airing the first two episodes back to back at 9.00 on Sunday 22nd on digital only channel BBC 3. It will gain a larger audience when repeated on Wednesday on BBC 2 which is also broadcast on analogue.

This is the slot in which, IIRC, The X-Files originally went out in some 15 years ago, before being moved to BBC 1 when it became more popular (I wonder if this will happen with Torchwood?)

There’s also a Torchwood: Declassified programme which presumably will be much like Confidential, but which it seems will strangely be first aired at 2.40am in the small hours of Monday morning.
