Brexit, then. The current Brexit barometer in the industry at today’s Frankfurt motor show is one of exasperation. Cheeks get puffed, shoulders shrugged, ‘you know as much as me’ often volleyed back over the net at the mere mention of the 'B' word when chatting with any car executive.

Whatever the outcome, a man more affected than most in the industry will be Jaguar Land Rover CEO Ralf Speth, who had a calm, articulate dissection of the current state of play on what it means for the UK's largest car maker.

“No one can give you an answer,” he said at today’s Frankfurt show. “And if they can, it will last two minutes before there will be another terms and conditions sheet.

“It’s difficult to make a judgement. I cannot predict the future. You can listen to the political statements and form different judgements even from that.

“I have 20-25 million car parts a day that need to be moved through our factories. I need them all just-in-time to be able to build a car. If I miss a part, the car isn’t built. There is no car.

“If there is a delay at the ports of one minute, two minutes, 10 minutes, or whatever - what happens? There’s talk of setting up warehouses to store these parts. Where am I going to store 20 million parts a day?
