OK, you’ve got two tasks.
Task one – to repaint the road markings on a road.
Task two – to resurface the road.
Do you (a) resurface and then repaint, or (b) repaint, resurface and then, er…, repaint again as you’ve just asphalted over your repainting?
I think you can guess which option Labour-run Haringey Council went for in Highgate.
