A little birdy tells me that the actor/actress chosen for the 12th Doctor will be announced tomorrow. No idea who #doctorwho #12thDoctor

But it ISN'T Ben Daniels. #doctorwho #12thDoctor

@Declan_May myself and a friend had a coffee yesterday and talked ourselves into Idris Elba

@KosmicKris Could be!He'd be excellent (bit older,mysterious,stuffed full with charm & gravitas).However,I've heard we'll all be surprised..

@sjcAustenite @emilyooo @theoodcast Ben Daniels was at long odds, we mentioned him on RFS, now he's 3/1 at UK bookies. FACT.

@Declan_May @Legopolis @sjcAustenite @emilyooo @theoodcast Blimey, that's quick! Will this be the most efficient succession in DW history?!

@JR_Southall @Legopolis @sjcAustenite @emilyooo @theoodcast I think they may have been pre-empted. Hope thats not why.

EDIT - Both BBC One and the show's twitter accounts have now denied any announcement. Steven Moffat's comments suggest it'll be a while.
