Did do rumba, in the middle Anton Du Beke messed up (12)

I believe the answer is:

mountebanked

'did do' is the definition.
(mountebank can mean to trick or 'do')

'rumba in the middle anton du beke messed up' is the wordplay.
'in the middle' means to look at the middle letters.
'messed up' is an anagram indicator.
The middle letter of 'rumba' is 'm'.
'anton'+'du'+'beke'='antondubeke'
'antondubeke' is an anagram of 'ountebanked'.
'm'+'ountebanked'='MOUNTEBANKED'

I've seen this clue in The Guardian.
