>I firmly believe that we should add an hour the year round; as Europe does.
You are mistaken. Parts of Europe are ahead of GMT, but then so is the rest of the world more than 15 degrees east of the Greenwich Meridian. Otoh, Portugal and the Spanish Atlantic islands are on the same time as GB.
>It's claimed that the far north of the UK has a problem of young children going to school in the dark. Start an hour later; it won't make a lot of difference at that age.
That's the trouble with basing opinions on "claims"; if the "claim" (or the understanding thereof) is wrong, so's the opinion. In this case, again, 'fraid you are mistaken.
