It’s because it’s political.I think there's so much more to come out about this guy, non stop news coverage for a someone that's on remand, searching vehicles at ports etc.
A few years ago a couple of seriously dangerous gangsters from Liverpool organised an armed escape and break out from a van whilst in transit in the Salford area. Think they were wanted for multiple murders. No where near any level of the coverage that this guy getting. Definitely not getting the full story, possibly because he's not been convicted (yet?).
Ali Khamenei has effectively pulled Sunak’s pants down and is giving him a damn good rollicking. It’s incredibly embarrassing for the Government - they are desperate to save face. The budget on finding this guy is unlimited for that reason. The guy will soon be hero No.1 in the Middle East if he isn’t already.
