Some more ignore rule (5)

I believe the answer is:

reign

'rule' is the definition.
(reign is a kind of rule)

'some more ignore' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'REIGN' can be found hidden inside 'more ignore'.

(Other definitions for reign that I've seen before include "Rule over in Niger" , "Period of the rule of a sovereign" , "Monarch's rule" , "Have sovereign power" , "Wield the sceptre" .)

I've seen this clue in The Telegraph.
