Yes, mostly harmless, the above does seem somewhat ironic. However, I believe that the seeds of where we are now in regards to Brexit were laid down in the Blair years. Many working areas, especially in the North of England were rapidly changed by large scale immigration over a relatively short period of time with inadequate consultation or information to existing residence of those areas.
It was also large scale resentment in the above areas to the large scale EU agency labour brought to the UK for low skill employment that was seen as undercutting local Labour as many of those agency workers were not even paid the minimum wage when the agencies deducted accommodation and food costs from their pay.
The above has cost the Labour party dearly in what was once it's heartlands of the North of England. However, it would seem that even those agency workers no longer wish to come to Britain to its now worldwide reputation as being an unwelcoming reputation of being an unwelcoming country for migrants or even those wishing to work here temporarily.
The above stated, for the Labour party there was very much some encouragement in the recent local council elections as Labour took Plymouth council. Here in the West country that is being put down to what is seen as this government "sell out" of the fishing industry in its staggering attempts to draw up a Brexit agreement which will save the London based finance industry. Also in regards to Plymouth was this government's lack of clarity in its defence policy.
In the above may also be seen how the Labour party may regain its Northern Heartlands, for if in the transition period or in the final Brexit agreement it transpires that EU agency labour will still be allowed to come to Britain, those northern areas will see "sell out" as the price they have paid in transition or final agreement.
However, it would seem even those EU agency workers do not at present wish to come to Britain.
