I opposed Merkel when she invited in a million refugees for further distribution within the EU, which at the time we were part of. She shouldn't make policies for every country in Europe. But that was the effect.
But if Germany houses and funds immigrants, that's never been a problem for me.
The trouble for the UK with Merkel was that a whole bunch of folks wanted to end up here. And we can't absorb disproportionate numbers. We don't have spare houses lying around.
More than happy to welcome a reasonable number of Ukrainians [no precise number for "reasonable" yet]. But I think the main burden should fall on Germany, because of its huge contribution to the issue.
Ukraine is under the cosh because Germany wanted cheap gas and was willing to pretend there was no problem with that and the dependency it created. But they fed the Russian monster.
