i mentioned it elsewhere too, that he is on asylum in UK, and when you take asylum, you voluntarily let go your nationality of origin.
Now, It isn't a simple thing to give Altaf his nationality back.
The thing is, It is very problematic. Altaf wants the nationality back, by which he'll be able to come back to Pakistan (basically, after Asylum he isn't allowed to travel back to Pakistan on UK Passport, Plus there are some cases on him, which disallow him to travel). So, what he really wants is that Govt of Pakistan , sends its envoy to bring him back to Pakistan, this way, UK won't interfere, as the Country of Origin is taking him back.
A political stunt, to get out of UK and go elsewhere in world, like UAE, Singapore etc.
