I believe the answer is:

ikea

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

'empire' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'part of mike ashley's retail' is the wordplay.
'part of' says the answer is hidden in the clue.
'IKEA' is hidden within 'mike ashley retail'.

Can you help me to learn more?

I've seen this clue in The Independent.
