Hi Guys,
Thanks for highlighting the link, I had not noticed it before. This looks like rather a common problem, I will take your advice and start by stripping the boot lining out.
There seems to be a plastic trim underneath the back window thats holding the side in place, and they seem to hold the floor panel in place. The plastic retainers seem very delicate does any body know how to get them out, is it simply prising them out gently or is there a special trick to it.
Don't suppose any clever sod has done a video of the operation have they.
