I'm a little stuck... Click here to teach me more about this clue!

'drive off i hear' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'discreetly queen enters ready' is the wordplay.
I cannot quite see how this works, but
'queen' could be 'q' (chess abbreviation) and 'q' is found within the answer.
'ready' could be 'on' (if a device is on it is ready for use) and 'on' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

'to' is the link.

Can you help me to learn more?

(Another definition for on the q t that I've seen is " Secretly".)

I've seen this clue in The Telegraph.
