This was a lovely bit of bad of driving. First there's the MGIF. Just has to get in front despite there being a red light ahead. Second, and this is where I think the MGIF shows the attitude, the driver enters the ASL (noting this wasn't an emergency stop to avoid cross the front line, but a plain slow drift into the ASL). And third, the final little move forward over the front line (technically a RLJ) just as the driver thinks I'm about to pass on the inside. Clearly the latter movements are designed to block off the ASL and any front position for me. So not even a mistaken slip into the ASL but a deliberate attempt to block it off.

As it happens, I'm turning left so am not sharing the road with this poor driving any more anyway.

Highway Code Rule 178 (backed up by the RTA).
Advanced stop lines. Some signal-controlled junctions have advanced stop lines to allow cycles to be positioned ahead of other traffic. Motorists, including motorcyclists, MUST stop at the first white line reached if the lights are amber or red and should avoid blocking the way or encroaching on the marked area at other times, e.g. if the junction ahead is blocked. If your vehicle has proceeded over the first white line at the time that the signal goes red, you MUST stop at the second white line, even if your vehicle is in the marked area. Allow cyclists time and space to move off when the green signal shows.
