I'm trying to get my head around the simple economics of the claims surrounding Port Talbot.

The claim is that the plant is losing £1miliion per day - There are 4,000 workers at the plant - let's be generous and say they earn an average of £35k each - that is a cost of £385,000 per day.

So over and above the cost of the workers the plant is losing more than £600,000 a day - on what, how?
