Some people think that Nawaz Shareef has more influence than British PM or PM's who already resigned, which is totally wrong.
This is not Pakistan where Nawaz can influence judjes and make suitable decisions for him. Nor Ch. Nisar can put any influence on Germany. This is recommended that Ch. Nisar should not provide any protection to Nawaz Shareef in this case, it may happen that German govt. issue arrest orders of Ch. Nisar for supporting Panama leaks victims.
