it's fairly clear that there is a political and an economic/ financial dimension to decisions about which countries are green/ amber/ red. The concection to incidence and varient statistics is... very, very tenuous.
Very much agree, especially the political link..
The policy wonks at Tory HQ will certainly have registered how popular just "stay the fark at home" has been and continues to be on opinion shifting/opinion shaping forums such as this and also such a message plays well with the Green lobby; in other words ATM there are votes to be had in being seen to be the party on be "hard on travel, hard on the causes of travel"..
, regardless of the underlying statistics.
There are also rumours that some at the Home Office have objections to opening up because they have serious doubts about their ability to police the Border if more travel is allowed......
If anybody thinks the restrictions are now just about protecting the UK population from a virus then "I have a bridge..."
P.S. With regard to the 116k figure for Brits in Portugal quoted above, of course they won't all be holidaymakers who have rushed off in the last couple of weeks..there are a lot of Brits who are permanent residents in the country.
