To be fair, the article makes plenty of reference to illegal migrants on boats across the channel - but yes, the main thrust is the high overall immigration numbers, projected to be record breaking this year. But how can they illustrate legal migrants? They can't exactly photograph a line of people at Manchester Airport because who knows who is whom?
It actually mentions “...the visibility of illegal immigration across the English Channel and that worries us and puts a big burden upon us.” plus "...the level of legal immigration is huge, it looks like we’re heading for a record year of net migration into the United Kingdom."
It isn't racist to think we can't provide the hospitals, schools, transport infrastructure etc. for an ever increasing population and it is wrong to throw that word around arbitrarily, there's a bit more to it than that.
