'bit of decor' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'city politician pursuing usual' is the wordplay.
'city' becomes 'LA' (Los Angeles).
'politician' becomes 'mp' (Member of Parliament).
'pursuing' means one lot of letters go next to another.
'usual' becomes 'standard' (synonyms).
'la'+'mp'='lamp'
'lamp' put after 'standard' is 'STANDARD LAMP'.
