'where leader passed' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'capital place to sleep i hesitate to say' is the wordplay.
'capital' becomes 'berlin' (capital of Germany).
'place to sleep' becomes 'bunk' (I can't explain this - if you can you should give a lot more credence to this answer).
'i hesitate to say' becomes 'er' (expression used when hesitating).
'berlin'+'bunk'+'er'='BERLIN BUNKER'
