Saw the interview with Pakistani politician Ishaq Dar. Dar is famously considered corrupt. Mr. Sackur had probably heard this but had done no preparation for the interview. His questions were uninformed, completely oblivious of facts, mis-cited documents, appeared nearly completely unfamiliar with the Pakistani context. When Dar have facts to refute Mr. Sackur's mis-accusations, Mr Sackur would either not let him speak by screaming over him or would change the topic altogether.
I would strongly urge the BBC to support the programme with some journalists, even at an intern level
