Beer drinking backbencher maybe on English vote: it’s a warning (7)
I believe the answer is:
example
'a warning' is the definition.
(as in making an example of someone)
'beer drinking backbencher maybe on' is the wordplay.
'beer' becomes 'ale' (I've seen this before).
'drinking' means one lot of letters goes inside another.
'backbencher' becomes 'mp' (backbencher is a type of Member of Parliament).
'maybe' becomes 'ex' (I can't justify this - if you can you should give a lot more credence to this answer).
'on' means one lot of letters go next to another.
'ale' going around 'mp' is 'ample'.
'ample' put after 'ex' is 'EXAMPLE'.
'english vote it's' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for example that I've seen before include "Characteristic item" , "Thing illustrating a general rule" , "Someone to emulate" , "Something illustrating a general rule" , "Ideal - specimen" .)
