North-country folk irksome Henry upset (12)

I believe the answer is:

yorkshiremen

'north-country folk' is the definition.
(people from Yorkshire)

'irksome henry upset' is the wordplay.
'upset' indicates an anagram.
'irksome'+'henry'='irksomehenry'
'irksomehenry' anagrammed gives 'YORKSHIREMEN'.

(Another definition for yorkshiremen that I've seen is " Northerners".)

I've seen this clue in The Times.
