Cabinet ministers will put into practice 'physical distancing' in their meeting on Monday morning as they grapple to get a hold of the Covid-19 crisis, with half dialing in via video-conference.
Parliament's powerful cross-party Business Committee will also hold discussions this week to determine how Parliament should operate at each alert level - including how many MPs to allow in the usually sardined debating chamber.

"It's not going to be acceptable to have 120 people in the same chamber at one time, because that automatically puts us over the limit [of 100 people for indoor events].
"We're going to have to be careful because MPs could be quite serious vectors... if we keep moving into groups and then moving out into the public."
