Dripping boot latch?

thoughts please!  Opened the boot earlier today, and noticed water dripping from the latch, it seems to be a recent occurrence, as there is no sign of rust, there is now a small puddle of water in the bottom of the boot, and again no rust, I am aware that the S does suffer boot leakage via the seals and, or the light clusters but both are dry, I was wondering if it's possible for water to ingress via the number plate fixings or the chrome jaguar plate / light / lock mechanism on the boot lid? 🤔 I will await you time served S owners input! 😁
