Removal of rear plastic valence

[pgm2008]

Hi I hope I'm asking this in the correct place !!
I would like to know how to remove the rear plastic valence of my MG Excite PHEV as it has suffered a small dinge which I'm sure will pop back out after applying a little heat and some gentle pressure.
Any help / advice would be greatly appreciated.
Thanking you in anticipation,
Richard G
