According to that article the shipment wasn't being supplied by the Turkish government. So why would they have made a request to them earlier before problems delivering it arose? The government said there was logistical problems. Makes sense they ordered them directly from a company and then asked the Turkish government for help when logistical problems arose.
I don't believe for a second that they told the public it was coming without an order having first been placed. And that article shows nothing to the contrary. If anything it suggests an export license was neglected by the supplying company, a procedure only instigated a month ago. Is that the UK govs fault?
