I don’t think it has changed and I agree its a disgrace, however if they ( the Ukrainian woman and children) arrived ilegally on a boat, I imagine they would would be greeted just like any other illegal - with open arms.
Pehaps some unpopular opinions here, but...
I think anyone about to drown in mid-channel SHOULD be immediately rescued, dried and fed, 'with open arms'. That is just a humanitarian necessity. And using that as an example of being 'soft' on immigration is sily and deceptive. The problem is finding a way to then send them straight back to France.
I don't really see why it is easy to deport to France a French yachtsman who has overstayed his visa, but impossible to deport to France an undocumented refugee/immigrant who has very evidently just left the French coast in a crappy dinghy.
Also, if Ukraine bordered the UK (like Poland) I would be saying "Open the border, and let in the refugees without restriction". And all credit to the neighbouring countries that have done this.
And if I ran a superstate like the EU, with basically no internal borders, I would be saying "Well, I suppose if the refugees are free to go anywhere in Poland, we might as well say they are also free to go anywhere in Schengenland, since we have no control anyway, and might as well sound all nice and humanitarian."
But if I ran an island nation, with borders, like the UK, I would be saying, "We are very happy to have our share of Ukrainian refugees, whether that is 10,000 or a million. But right now the refugees are reasonably safe and comfortable in Poland (and we have just sent the Polish government £100m to help pay for their welfare), so we think we should take a few weeks to make sure that the refugees who are likely to be most comfortable in the UK (due to connections, relatives or whatever) come here, not just the first random people who happen to have crossed the border. "
But I think HMG has messed this up by blustering about security checks aand bureaucratic bottlenecks, and spinning about how good we are on refugees, rather than being both vigourously welcoming and setting a meaningful threshold.
