From the Guardian reporting on press conference with BJ et al:
“Q. How long can people stay at another person’s private garden, can you go inside to use the loo and when can we hug loved ones again?
Johnson says no to overnight stays as we’re not at that stage.
All of these adjustments have to be in socially distanced way, with people continuing to wash their hands and use common sense, he adds.
We can’t move freely across the country to stay at other people’s houses, he adds.
Whitty says the two metre rule is critical because the virus spreads in air droplets.
After using the loo, wipe everything down and wash your hands, he adds.
Plus if you’re passing things from one person to another, e.g. when doing a BBQ, you must be washing your hands and wiping everything down, he adds.”
Which perhaps means you can use the loo and share food. All a bit vague.
Still, it’s welcome news.
