I wonder if the sweeping emergency powers they implemented, almost unopposed, during COVID gave them a new vigour for thinking a universal method of surveillance might be a good idea. I think ‘voting fraud’ is as much of a red herring as ‘terrorism’ was back in 2002.
What 'surveillance' would an ID card give though? We are all already surveilled every time we walk down the high street or draw money from the cash point, use the internet from our homes or use our mobile phones.
If by 'surveillance' you mean monitoring how people access the benefits system, social housing, the NHS, undertaking paid work, their immigration status, their criminal history and their eligibility to vote, then bring it on, I say.
