I guess having three services with identical content (Two, Scotland and News) is a different story to just two?
That shouldn't happen though, at least not regularly, as Scotland won't start till after the news simulcast has finished.
Something like PMQs will presumably end up on 4 channels, but Parliament's coverage is different to News' and BBC Two's... and they'll all naturally have different delays as they're produced seperately
No, this loop will continue until 7pm Sunday 24th Feb. This is the sustaining feed that will play between 12am and 12pm when channel is live with a few small variations.
