Workplace in The House leading to the foreign government's department (4,6)
I believe the answer is:
home office
'department' is the definition.
(I know that Home Office is a type of ministry)
'workplace in the house leading' is the wordplay.
'workplace' becomes 'office' (I've seen this before).
'in the house' becomes 'home' (to be home is to be in your house).
'leading' means one lot of letters go next to another.
'office' after 'home' is 'HOME OFFICE'.
'to the foreign government's' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Another definition for home office that I've seen is " Government department".)
