BBC will use Studio B at BBC Broadcasting House, with the BBC One news programmes moved out into Studio E again whilst they prepare the set and rehearse, probably for two weeks before the election night. I don't see them using the vast studio presentation style they used to use up to 2017. I think that era is long gone, and the amount of money to fill Studio D at BBC Elstree would just be a waste for the already strapped for cash BBC

I wonder if BBC One news would still need to move out, as they didn't last year(?) when it was used for election coverage.

Potentially by the time the election is called the One will have moved to Salford. This will mean that the studio is free on weekdays until around 5pm, allowing for daytime rehearsals. The main thing which will need adding is the 'mega-desk', which last time remained present during the national news bulletins and LK in the days/week prior, and for a few days afterwards. Maybe they'll also add the bits to the curved wall section as per LK, so that interviews can be done from that area.

Unlikely the last general election they won't need to take B out of use for a couple weeks to install (and later remove) a touchscreen, which replaced part of the normal set. The touchscreen is already part of the existing set, though rarely used in that way these days.
