Toilet leaking on flush

[redconker]

Hello,

I have an Ideal Standard toilet which is leaking clean water when I flush. I don't think it is the coupling or the toilet system. Underneath the toilet pedestal there are two openings which I can only guess are to allow airflow during the flush and water is coming from there. Any idea if these holes should have been left open (I didn't install the toilet), what they're used for and where I would start in resolving the leak, please?

Here are some pictures:

New close coupling kit is needed:
