Who is R. Westfield from Burmese Days and what is their importance?

Westfield is sandy-haired and has a prickly moustache, with wide-set grey eyes and abnormally thin calves. Westfield speaks in clipped and soldierly prose and appears to intend most of his own statements as jokes. He is the District Superintendent of Police. Westfield is outspoken in his racist views, though he does take pride in the capabilities of his local police force, consisting entirely of native Burmese. It is interesting to note that Orwell, the author, was a police officer during the period he spent in Burma.
