Since when were Welsh people classed as immigrants?

If you are trying to score cheap points off me btline I'm afraid I'm going to have to point out in defence of myself that what I was commenting on was the word "migrants" - not "immigrants", a word which has entirely different connotations.
"Local governments should make efforts to encourage migrants to learn English and integrate"
Migrating suggests travelling back and forth, which is precisely what Welsh people do every time they cross the border into England. And as I say, most already speak English in any case.
