Trickster's gossip in support of British ruler (4,6)

'trickster's' is the definition.
(trickster character in a series of stories)

'gossip in support of british ruler' is the wordplay.
'gossip' becomes 'rabbit' (rabbit can mean to gossip or chat).
'in support of' says to put letters next to each other (I've seen this in other clues).
'british' becomes 'br'.
'ruler' becomes 'ER' (abbreviation for Elizabeth Regina).
'br'+'er'='brer'
'rabbit' after 'brer' is 'BRER RABBIT'.
