The little mirror on the top left of the windscreen?

I had a look at that, and whilst obviously I couldn't see it that well from where I was standing it didnt' look like it was positioned in such a way that it would show the area in front of the left had side of the cab.

It looked like it was angled in such a way as to show the area in front of the right hand side, but it would have needed to have been rotated maybe 15-20 degrees to have shown the left.

Yes, that's the class vi mirror. Hopefully, the police will check the position of the mirror relative to the driver's position (eye-height) in the cab to establish its field of view.

If this mirror is correctly set-up (and the correct mirror has been used), it should show what is to the front left of the vehicle.

There's a lot of info here on LGV mirrors and their respective fovs: http://www.truckview.net/TRLreport.pdf
