snapped rear spring

[rs32]

driving down from Scotland yesterday - had a massive CLANG at 80mph on the motorway. Sounded horrendous.

pulled in at services immediately, checked the car, nothing obvious. So drove off and immediately hit a bump that caused a loud rattle from the rear right.

pulled in before I got to the motorway again and checked the car, it seemed to be leaning to the right on a camber that went left and I couldn't get my hand between the tyre and wheel arch on the rear right.

car now being trailered to local dealer, Mondial Assistance were a bag of shite and it fell to me to get everything organised properly.

is there anything else in particular that I need to get the dealer to check ? Am concerned maybe that there is another problem e.g. top mount, RTAB etc ?

Any pointers would be appreciated.
