Some risk-takers are betting on those local clashes over popular Government Bill from Labour leader (6-6)

'some risk-takers' is the definition.
I can't tell whether this definition defines the answer.

'betting on those local clashes over popular government bill from labour leader' is the wordplay.
I cannot quite understand how this works, but
'betting' could be 'gaming' (gaming is a kind of betting) and 'gaming' is present in the answer.
'bill' could be 'tab' (a tab is a bill at a bar) and 'tab' is found within the answer.
'from' could be 'e' (I've seen this in other clues) and 'e' is found in the answer.
'labour' could be 'l' (political abbreviation) and 'l' is located in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'are' acts as a link.

Can you help me to learn more?
