'leader voiced concern for home buyers?' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'yours truly labour' is the wordplay.
'yours truly' becomes 'I' (the person who set this crossword).
'labour' becomes 'kea' (I can't explain this - if you can you should give a lot more credence to this answer).
'i'+'kea'='IKEA'
