English parliamentarian with Queen — or another ruler? (7)
I believe the answer is:
emperor
'another ruler?' is the definition.
'emperor' can be an answer for 'ruler?' (emperor is a kind of ruler). I'm not certain of the 'another' bit.
'english parliamentarian with queen or' is the wordplay.
'english' becomes 'E' (abbreviation).
'parliamentarian' becomes 'MP' (Member of Parliament).
'with' says to put letters next to each other.
'queen' becomes 'ER' (short for Elizabeth Regina ie Queen Elizabeth).
'e'+'mp'+'er'+'or'='EMPEROR'
(Other definitions for emperor that I've seen before include "He rules over several states" , "Supreme ruler" , "Napoleon Bonaparte, for instance" , "Beethoven's Piano Concerto No. 5 in E-flat major" , "Male ruler of a group of countries" .)
