Every country has a different population size which means the total number of deaths needs to be normalised in order to be comparable.
Belgium has the highest death rate per million population in Europe - 79.25
The UK is 4th in Europe behind Belgium, Spain and then Italy.

The fact we're 4th does warrant some concern as Spain and Italy were hit hard before us.
But then all these death statistics are compiled using different definitions anyway, so there's no useful direct comparison right now.
Belgium, for example, include all suspected covid deaths in their figures whereas the UK does not.
So probably best not to jump to conclusions until some thorough and rigorous global modelling/analysis has taken place.
