Consider red rag unsuitable (6)

I believe the answer is:

regard

'consider' is the definition.
(I know that consider can be written as regard)

'red rag unsuitable' is the wordplay.
'unsuitable' indicates an anagram (letters not in suitable order).
'red'+'rag'='redrag'
'redrag' anagrammed gives 'REGARD'.

(Other definitions for regard that I've seen before include "Look at - estimation" , "Care" , "Gaze at; esteem" , "Concern" , "Look - respect" .)

I've seen this clue in the Evening Standard.
