Apparently, Elle, Kentish Town has no connection with Kent.
Mr Google reckons the name comes from "ken-ditch", meaning "bed of a waterway". It was a community which grew up beside the River Fleet.
I am disappointed in The Times, today, with a clue.
25, Dull-witted Apache for one, lacking heart and energy (5)
Answer, " inane".
Parse is Apache = Indian, lacking heart= inan, with e for energy, giving inane for dull witted.
But, the Apache people were not Indian, they were/are Native American.
Wonder how Richard Rogan would justify this clue?
