Spokescritter with a British accent (5)
I believe the answer is:
gecko
'spokescritter with a british accent' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gecko that I've seen before include "Type of lizard" , "Malaysian climber" , "Small tropical lizard" , "Lizard noted for ability to climb smooth surfaces" , "one climbing the walls?" .)
