Series 7 of Doctor Who will begin airing on either Saturday 25th August or Saturday 1st September.
The possible airdates come after the announcement that Episode One of Series 7 will be getting its premiere at the MediaGuardian Edinburgh International TV Festival in August.
The festival, which takes place between 23rd-25th August 2012, will be screening the new Dalek episode (rumoured to be titled 'Asylum of the Daleks'), as well as hosting a Sherlock Masterclass led by Showrunner, Steven Moffat, Co-creator, Mark Gatiss, and Producer / Wife of The Moff, Sue Vertue.
DWO have therefore deduced (see what we did there) that Series 7 will either get its BBC One premiere on Saturday 25th August, or Saturday 1st September.
