Freedom! Fishermen can net flounders! (15)

I believe the answer is:

enfranchisement

'freedom' is the definition.

'fishermen can net flounders' is the wordplay.
'flounders' is an anagram indicator (I've seen 'flounder' mean this).
'fishermen'+'can'+'net'='fishermencannet'
'fishermencannet' anagrammed gives 'ENFRANCHISEMENT'.

I've seen this clue in The Independent.
