So, let me get this right.

The government commissions a report from it's own people.

The report is duly put together to inform the government of the likely outcomes of a no-deal Brexit such as delays at ports, immigration delays, disruption of medical supplies, a shortage of some foodstuffs, the potential closure of two refineries etc etc.

The government should then, according to your somewhat skewed notion, ignore that very same document as "project fear"

What !!!!!!!
