Radiator Leak Vauxhall (Opel) Zafira?

My brother has a Vauxhall Zafira 1.6 petrol (with air conditioning) which is leaking coolant,he tried radweld but to no avail. I had a look at her and it seems to be coming from the drain valve/plug in bottom middle of the radiator (not sure exactly what it is). Can you buy a new one of these (can't find any trace of one on ebay) or will t mean a new radiator? Thanks in advance for your help.

Update:

Where the leak is there is what looks like a bolt thread with a rubber thing at the top.
