Irishman maybe leading disturbance: one proud of his country? (7)
I believe the answer is:
patriot
'one proud of his country?' is the definition.
(a patriot loves their country)
'irishman maybe leading disturbance' is the wordplay.
'irishman maybe' becomes 'Pat' (Patrick is a common Irish name).
'leading' means one lot of letters go next to another (some letters go in front of others).
'disturbance' becomes 'riot' (I've seen this in another clue).
'pat'+'riot'='PATRIOT'
(Other definitions for patriot that I've seen before include "Loyalist" , "A trip to (anag.)" , "Chauvinist" , "Defender of country" , "One defends his country" .)
