No shortage of news today. Australia wildfires and US embassy in Baghdad perimeter breached by protesters for 2nd day running for example. If it wasn't for BBC1 trying to fit too much into their schedule tonight, a more usual length bank holiday news bulletin could easily have been filled. Plus even if it had turned out to be a quiet news day, a sports bulletin could have been included.
Probably, though unlike Christmas Day there was an early evening bulletin (and it was a normal bank holiday duration)
