The subliminals on the graphic are interesting. A change from red hatching (red for danger) to green hatching (green for go).
I didn't notice that. It's interesting because nothing in Boris's speech last night said it was time for us to "go". All he's given us so far is "you can exercise as much as you like and that includes sitting in the park". For a lot of people that just brings the rules in line with reality.
ETA: Oh and you're allowed to travel to work even if your job is non essential.
And why wasn't this put before parliament?
Because it doesn't need to be.
