Point at last part of London (4,3)
I believe the answer is:
east end
'part of london' is the definition.
(I've seen this before)
'point at last' is the wordplay.
'point' becomes 'east' (east is a kind of point).
'at' means one lot of letters go next to another.
'last' becomes 'end' (I've seen this in another clue).
'east'+'end'='EAST END'
(Other definitions for east end that I've seen before include "London Cockney area" , "Side of London associated with Cockneys (4.3)" , "Cockneyland" , "part of the capital" , "ockney London" .)
