I just watched it all. It was so brutal that even as a PTI leaning person I felt bad.
Now the question is who gave this genius idea to have him appear before British media? And why now? I think this only happened or got decided in a state of panic. Remember before Panama leaks came, NS son gave an interview to Hamid Mir and without any probe or question, started to give clarifications about some offshore properties (even Hamid Mir was surprised that why is he even mentioning this). Few months later Panama revelations happened regarding the same properties....
I think NS and co have smelled a similar potential danger that required them to take this drastic risk of sending Ishaq Dar to BBC. I am not sure what that danger is - but there definitely is a panic about something, otherwise they could have just used their bots in the Pakistani media to do their usual bidding.
My guess is that some progress may have been made about their repatriation back to Pakistan or IK may personally be lobbying and asking UK govt to facilitate their departure from UK (besides deportations or extradition they could time limit their stay here). This interview may be one of those hasty preventive move - and oh boy just like the last move it has so badly misfired.
These guys thought that with their now open anti-Army rhetoric they would get a friendly ear from British media, but nope - Hard talk host decided to call out the usual BS corrupt politicians usually throw. They didnt understand that western media journalists are proper journalists who have seen the world - they deal with so many pieces of sh**s like him and are aware of all the different types of BS these criminals come up with for their illegal wealth such as: its all a conspiracy, I am sick, I am clean as an angel, I have no money or properties, I am broke, deep state after me bro, rigged elections, what properties? My opponent lies so much and broke his promises? My opponent is hitler! My properties... ah really, what about what his interior minister said? Etc.
