Everyone ( Most ) of us know very well that such letter will have "ZERO" impact :)
UK will not handover neither Nawaz Shareef nor any political leader to Pakistan.
Such letters are either to fool normal public or just to creat heat in Pakistani politics.
What should Government do ?
Government should ask now those Judiciary and those who gave guarantee that Nawaz Shareef will come back .
How and when Nawaz Shareef will come bcak to Pakistan ?
He will come back to Pakistan with a guarantee that nothing will happen to him and he will be a free person after some small judiciary work .
Who can give such guarantee ?
Only Establishment can give such guarantee .
Is Establishment ready to give such guarantee ?
No
Is it possible that Establishment will divide on Nawaz Shareef matter ?
NO chance . They look like aggreed to give some relief to PML-N but not to any Shareef's family .
How long this situation will go ?
Till MINUS SHAREEFS from PML-N .
Why Establisment is not ready to give any chance to Shareefs ?
Last time Nawaz Shareef showed his "vendetta" only against one General but this time he has a full package for several of Establisment person.
To understand "the mind condition of Establishment about Nawaz Shareef " , you must read in detail
" Why does Robespierre of France faced " Execution" ?
Because no one in his own party was not sure who will be the next to get " Execution " on the instruction/wish of his own party leader (Robespierre) . Everyone was afraid that he maybe the NEXT .
And that is why they decided to Execute Robespierre to save their own life .
In my view " Shareefs " has very less options remain and particularly " Nawaz Shareef"
Let see what happen in next some months or some years from now !!!
