Wow. I'm embarrassed to be the same citizenship as this idiot.
The causal link may be sufficient evidence to get him at least something out of the case unless BA can prove that it was still primarily his fault.
And what ridiculous journalist finds any value in including a corny line such as:

At best, pointless reporting.
My gut tells me that he will still get something substantial. Maybe not $600,000, though. But much more than a GBP 50 High Life voucher and a letter of apology.
