I'm a little stuck... Click here to teach me more about this clue!

'basket in sport for discussion' is the definition.
'webinar' can be an answer for 'discussion' (I have seen 'online discussion' mean 'webinar' so perhaps 'discussion' could also mean 'webinar'). I'm unsure of the 'basket in sport for' bit.

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for webinar that I've seen before include "Internet seminar" , "online discussion" .)

I've seen this clue in The Guardian.
