Some men of Pakistani origin in the United Kingdom committed some grave sex crimes against children. These men are British citizens and they have served prison sentences for their offences. To be sure some of these crimes were heinous.
It is quite wrong to take away their citizenship. These people have already been heavily punished. They have suffered their prison sentences. Moreover, they have been branded with the P word. This is a terrible stigma to carry around. I am not saying they do not deserve it. They will face an uphill struggle to ever secure employment again.
Processes have been entered into to deprive these men of their citizenship. They will then be deported to Pakistan. This is unjust. It would be punishing them twice over. It is related to the double jeopardy principle.
It is true that were these men booted out of the United Kingdom then the country would be safer. However, that is not the point. Justice must take priority. To take away their citizenship would be to create second class citizens. British born persons would have a higher grade of citizenship than naturalised persons.
Had these men committed such crimes before being granted citizenship then it would have been right not to give them citizenship. But now that they have it they should never have it taken away.
This is why one must be very circumspect about granting citizenship. That is because it should never be taken away. That includes for murder. I would require 10 years residence without claiming benefits and with no criminal record and paying GBP 10 000 to secure it. That is not as stringent as the requirements in Switzerland.
