'across road you and i celebrate cabinet member' is the definition.
I can't tell whether this definition defines the answer.

'across road you and i celebrate cabinet' is the wordplay.
'across' means one lot of letters goes inside another.
'road' becomes 'street' (street is a kind of road).
'you and i' becomes 'we' (we means you and I).
'celebrate cabinet' becomes 'sing' (I can't explain this - if you can you should give a lot more credence to this answer).
'we'+'sing'='wesing'
'street' put into 'wesing' is 'WES STREETING'.
