I believe the answer is:

sinn fein

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

'party in ireland' is the definition.
'sinn fein' can be an answer for 'party' (Irish political party). I'm not certain of the 'in ireland' bit.

'small pub organised fine' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'pub' becomes 'inn' (an inn is a type of pub).
'organised' indicates anagramming the letters.
'fine' is an anagram of 'fein'.
's'+'inn'+'fein'='SINN FEIN'

Can you help me to learn more?
