Under bathroom sink leak

[Jay003]

Hi there. Hoping someone could give me some advise please. I’ve noticed below the sink, water pooling up in the cupboard located under the sink. Having looked at it whilst the tap is running I’ve located where it dripping from but no idea how to fix. I’ve taken a couple of pictures to illustrate and the water drip is visible at the very top.

Any help very much appreciated!

Note the word "basin" in andy's link.
It's not a sink!

Don't think a basin mate would work with that setup, it looks like a vado universal click clack or captive waste.

OP, you'll need to take the waste apart, out of the basin and seal it back up with a little silicone
