Wishes to cross road left by independent young peers (9)

'young peers' is the definition.
(young lords)

'wishes to cross road left by independent' is the wordplay.
'wishes' becomes 'longs' (to wish for something is to long for it).
'to cross' means one lot of letters goes inside another (some letters cross or go round others).
'road' becomes 'rd' (abbreviation).
'left by' becomes 'l' (I've seen this in other clues).
'independent' becomes 'i'.
'rd'+'l'+'i'='rdli'
'longs' going around 'rdli' is 'LORDLINGS'.
