That is how propaganda has always been done in Britain. Unusual for direct lies, it is what they don't tell you that misleads.Assuming that is true, Johnson should have kept his bl@@dy mouth shut until he knew the facts/ was happy to reveal them. My mother died a couple of years ago at the age of 96, they wrote stuff on the death certificate but her body was just worn out; it sounds like for this person it might have been the straw ... It might just as easily been a flu or heavy cold that caused it.
I am undecided whether it has become less subtle in recent years due to the propagandists now being up against everyone being able to check their stories online against other sources, or because whether due to being able to check with other sources means I'm now aware of their game.
A good example of this is the 45 minutes from Saddams Weapons of Mass Destruction claim. They were right that part of the UK was within 45 minutes range of Saddams missiles, but didn't think it necessary to mention that the part of the UK that was was the British Sovereign Bases in Cyprus.
I think they had actually convinced themselves that he still had chemical weapons, whether said weapons if they still existed could have been put in a missile tip is another matter altogether.
I think in this case Boris and co are frightened they will be criticised for not locking down fast enough in 2020 in a future public enquiry and are now panicking and imposing all sorts of precautionary measures just in case all the evidence about Omnicron being mild is wrong, so they cover their rears.
A decent politician with a majority of 80 would have just appointed a retired Supreme Court Judge to lead the enquiry, namely Lord Justice Sumption, and metaphorically given the finger to opposition and press howls of protest. (Blair did just that with the Dr David Kelly inquiry)
