The UK has always had a certain reputation in many countries abroad of being competent and organised. That reputation translates into soft power. It beings increased respect for British businesses and business people, and helps foster trust.
Of course it does not mean that every British business person or business is respected or trusted. But the assumption that Britain in general is competent and organised does affect people's assumptions and views of British business.
I think that is eroding fast. Every friend and family member abroad I have spoken to has see that video of the nurse crying and I have been asked a few times why our supermarkets are empty of food (I know they are not, but that is the impression some of they now have). They ask me why British people are not co-operating when in their own country there is no evidence of stockpiling and the only shortage is hand sanitiser. They ask me why we don't have enough PPE for medics.
Some of these questions are by people who pay attention to the news, but everyone has seen the video of the nurse crying.
So AIBU to think Britain is losing a lot of soft power and that this will have an impact on British businesses abroad.
