One of the strands of thought on this thread is that vaccine should go from the UK to the EU, because case numbers are increasing exponentially on the continent and their need is greater.
This is a position I could have a certain sympathy for, were it not for three points.
Firstly, we're much smaller. Even if we diverted it in it's entirety the impact would be small. This is political posturing to save arses, rather than health policy to save lives; the UK supply simply isn't big enough to make much impact on the latter.
Secondly, if we're redeploying on the basis of need, there are plenty of places in greater need than the EU. That would include Papua New Guinea, to whom the EU are currently blocking supply.
Thirdly - and this is the big one - if the EU wants that they're going about it all wrong. They could try, you know, asking? Showing gratitude? Offering to pay for the doses they've taken? Perhaps, in the same spirit of shared neighbourliness, offering to help with the Northern Ireland border mess?
Instead they've acted like a spoiled toddler at a party, holding all the sweets to their chest and crying, "mine mine mine!". If, instead of saying, "We demand parity!" they said, "We're hurting, can you help?", then I rather suspect the UK response might be different.
