The new Season premieres in two weeks and three days time on Saturday 11th May 2024. This premiere also aligns (on linear television) on the night of the final of the 2024 Eurovision song contestant with the BBC marketing it as a “Whorovision” night! Whorovision Night will see the first two episodes “Space Babies” and “The Devil’s Chord” airing back-to-back, as such I for one am guessing that both episodes will have their BBC IPlayer premiere at midnight!:

(Great to know that I could well be running twice as late with BGT auditions and possibly even The 1% Club on too that night. I’ll have to see whether or not I can get to them both before the linear premiere).
Sidenote: I would usually try to use a BBC Source, however they haven’t published anything about it and as such I’ve been forced to use the Digital Spy source (This weeks issue of What’s on TV magazine also teases this too by the way). I think the BBC have an advert out that confirms that to be the release date though.
