Topples in shortened pants (9)

I believe the answer is:

dethrones

'topples' is the definition.
(I've seen this in another clue)

'shortened pants' is the wordplay.
'pants' indicates an anagram (UK informal term for 'nonsense' or 'rubbish').
'shortened' with letters rearranged gives 'DETHRONES'.

'in' acts as a link.

I've seen this clue in The Guardian.
