This junction must be a huge money earner.
TBH, you do look to be totally bang-to-rights on the actual contravention, because you entered the box and instead of ducking in to your left where there seems to be a space, you just stopped behind the gold-coloured car that came in alongside you on your right, and took the space on the other side of the box. This is the classic contravention scenario !
Can you tell us more, at all ?
