The Brits themselves. The UK auto industry needs to do some soul-searching. In the past, the laissez-faire relationship with the Tories was obviously good enough for it to be able to sell off all UK car brands (except Morgan). So it became completely dependent on what's decided by the new foreign owners and investors. Now that UK car plants have to fear for their existence, the relationship clearly isn't that great that the UK auto industry could prevent the Tories from stubbornly pursuing Brexit. The bitter irony! An orderly Brexit is negative for the UK auto industry, a no-deal Brexit would be devastating!
