Nowhere in the same league as saying " U.K. Government has been busy killing its own population this year " That's straight out of the sinn fein big book of lies.I don't think there's any accurate way of determining how many people have really died from Covid 19. Everybody seems to have a different system of collecting data and some countries are massaging the figures to make themselves look good.
It's a bit simplistic to say that Ireland and New Zealand should have the number of deaths based on similar sized populations. For instance NZ is in the arrse end of nowhere and can stop people entering the country quite easily. The ROI on the other hand has a land border with the UK and people can freely move from one jurisdiction to the other. And there's not much to stop people from all over Europe moving to both countries either.
But if you want to work on raw figures of deaths per population; Ireland's is 345 per million while the UK is 608 per million. Russia and China are claiming their deaths to be ludicrously low, 45 and 3 per million respectively, and I'd simply dismiss them as bóllocks.
