Rear Backrest Removal issues

[buzz887]

Hi,

i need to remove the the rear backrest on my MgZT.

Water is coming in to such an extent that it is flowing under the rear seat cushion and at the same time both rear seat cushion and backrest are waterlogged.

Water has progressed under carpet so its a nightmare situation.

I have removed the rear seat cushion but am having major problems removing the backrest. The backrest is a the fold down type.

Any assistance please i just cant seem to release/ unhook the backrest?

many thanks
