Well as I had to get the job done, I couldn’t wait for replies so here is my prognosis. (Ooh that’s a big word) lol.
Firstly I masked off all my paintwork to prevent damage.
Then, as I didn’t have any plastic bodywork tools I used a broad bladed screwdriver to gently prise off the chrome strip. This levers off from the top, not from the bottom.
Next I loosened off the clips on the right hand side by again gently prising them forward with a wide chisel.
This is where you have to be careful.
As the right hand side of the bezel is wider, you would think the bezel would slide off to the right, “NO” it slides slightly to the left.
Had I known this I may not have broken two lugs off the bezel.
Realising this (to late) I gently prised of the left hand side of the bezel.
Note, let the lugs give up on there own, don’t be tempted to pull the bezel by ripping it off. I used a long screwdriver to gently ease the rest of the lugs out by putting the screwdriver in between the bezel and the bumper, from the right hand side.
Well it’s off and reusable with the two broken lugs plastic welded back on.
Hope this helps anyone else attempting the job.
PS, plastic trim tools may have been a help.
