A classic example of this was the difference between two adjacent wards -
#eastputney and
#westputney - separated from each other by a road called
#putneyhill . There was a difference of nearly 10% in voter turnover between the two in May 2022. The ward with the higher turnout -
#westputney - had a paper thin margin for
#labour over the
#conservatives - as measured by the average vote per candidate in a three member ward. The ward with the lower turnout had a modest margin the other way.
