Maizie
It's called governance Maizie and whether it be the Financial Crash in 2008, Brexit related issues now it again matters not one jot.
I simply want a government and our politicians on both sides to use the tools to cope with the continuance of industry/manufacturing/jobs , the same as any other country worth it's weight in salt would do, indeed does do .
If suppose the Italian Banks crash (they are in a terrible mess ) , Greece goes belly up, the Euro nose dived and the World Financial System crashed that would not be caused by Brexit would it!
If that happened then it us incumbent on the government of the day to protect the interests of the UK as best as it can, using the tools to do so.
That is called 'Governance'.
