It is interesting that a few people on here don't seem to understand the Proportional Representation system that is used for EU elections.
You only vote for a single party and then the proportions are calculated. After the 1st MEP is elected, then that parties vote is divided by 2 and then the person with the next highest number is elected, continuing until the necessary number of MEPs has been selected.
The constituencies are much bigger than for WM elections: the whole of Scotland for example, and the whole(?) of London.
Continuing those examples, Scotland has 6 MEPs and London has 10 (I think). They are elected according to the d'Hondt system which in theory ensures that the seats are allocated proportionally (although the parties receiving the smallest percentages may not count). I think the North East is one of the smallest regions, returning only 3 MEPs.
There is no such thing as a "safe" seat.
Scotland last time returned 2 SNP, 2 Labour, 1 Conservative and unfortunately 1 odious and execrable UKIP MEP (the 1st ever and still the only elected UKIP representative at any level in Scotland) - who replaced the longstanding LibDem MEP
It was a relatively close call between a 3rd SNP MEP and a Green MEP. This time round they are projecting 3 SNP, 1 Labour, 1 Green and a 4 way tie for the 6th MEP amongst a 4th SNP candidate, a Conservative, a Brexit party and I can't remember if it was Labour or Green.
