Team leader occasionally lacks a bipartisan view? No! (7)

I believe the answer is:

captain

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

'team leader' is the definition.
(I've seen this in another clue)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for captain that I've seen before include "eg Hornblower" , "Ship's commander" , "One traditionally goes down with a sinking ship" , "Lead (a team)" , "Naval rank" .)

I've seen this clue in The Independent.
