Claimant legally keeping cloak (6)

I believe the answer is:

mantle

'cloak' is the definition.
(mantle is a kind of cloak)

'claimant legally keeping' is the wordplay.
'keeping' says the answer is hidden in the clue.
'MANTLE' is hidden within 'claimant legally'.

(Other definitions for mantle that I've seen before include "Robe or gas-lamp fitting" , "A cloak, cover" , "Gas lamp part; cloak" , "Loose cloak, shawl" , "Lament in loose cloak" .)

I've seen this clue in The Times.
