Prominent Victorian dancing ladies, one entertaining Queen (8)
I believe the answer is:
disraeli
'prominent victorian' is the definition.
(Benjamin Disraeli)
'dancing ladies one entertaining queen' is the wordplay.
'dancing' indicates an anagram.
'one' becomes 'i' (Roman numeral).
'entertaining' indicates putting letters inside.
'queen' becomes 'r' (r is abbreviation regina. e.g. in ER ).
'ladies'+'i'='ladiesi'
'ladiesi' is an anagram of 'disaeli'.
'disaeli' placed around 'r' is 'DISRAELI'.
(Other definitions for disraeli that I've seen before include "Old Prime Minister and novelist" , "prime minister, in the past" , "Benjamin ..., British prime minister" , "Raise lid on this old British prime minister" , "Ali dries out the old British prime minister" .)
