Aygo 2006 boot leaking

[Bluemel2529]

My 2006 Aygo the boot is leaking I have so far fixed the top break light as it was leaking from there a bit but it's stil leaking and I get water in the left and right corners of the boot behind the back lights like it could be dripping down the wiring loom in to the floor of the boot , but I'm not sure we're it is coming from I'm next going to sealant the back lights and the rubber gromits , is there any were else it could be coming from ?

I have seen some talk about water ingress in the boot, and aparently there's two vents behind the bumper and water can come in there. Some people tend to block those vents off completely and seal them up.
