Well of course HMG has been in denial about such issues for years ever since they forecast just a few tens of thousands of EU migrants would come here after the EU expanded. The result of this is that resentment, intolerance and fear grow in both the host and migrant communities as public services struggle to cope with demand. These problems were entirely foreseeable as soon as it became clear that the numbers involved were massively underestimated yet HMG has been very slow to act where they've done so at all. Sadly, these problems will only get worse as the economy continues in the doldrums and when the cuts which are going to have to be made start to bite. The tactic used to be to brand anyone who raised such questions as racists/xenophobes but when they realised they couldn't get away with that anymore they started promising an open debate about these issues...
One thing that hasn't changed, however, is the apparent lack of any meaningful plans or measures to address serious problems like these.
