The passenger side drainage hole to the rear (i.e. the one you can see on the left when opening the boot, next to the boot hinge), appears to be blocked as it is full of water. Any ideas how to un-block it, as there is no obvious obstruction I can see.
On other cars I found the best thing to clear these drains was a length of strimmer cord - the heavier the better (heat the end in a flame to round it off first) - no art to it, just push it in gently & wiggle it about.
