Ignore vandalized district (6)

I believe the answer is:

region

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

'district' is the definition.
(I know that district can be written as region)

'ignore vandalized' is the wordplay.
'ignore' anagrams to 'REGION'.
Though, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for region that I've seen before include "Part of a country" , "Wide area" , "Area, territory" , "Area,territory" , "Area - district" .)

I've seen this clue in The Times.
