Lenders with plenty travelling in glorious style (13)
I believe the answer is:
resplendently
'in glorious style' is the definition.
(in a glorious or splendid way)
'lenders with plenty travelling' is the wordplay.
'with' is a charade indicator (letters next to each other).
'travelling' indicates anagramming the letters.
'lenders'+'plenty'='lendersplenty'
'lendersplenty' is an anagram of 'RESPLENDENTLY'.
(Other definitions for resplendently that I've seen before include "In an impressively beautiful manner" , "Brilliantly" , "In a sumptuously impressive way" , "Magnificently" .)
