Government department which became vital during lockdown? (4,6)
I believe the answer is:
home office
'government department which became vital during lockdown?' is the definition.
'home office' can be an answer for 'government department' (I've seen this before). I am not certain of the remainder of the definition.
'government department' is the wordplay.
'government' becomes 'home' (I can't explain this - if you can you should give a lot more credence to this answer).
'department' becomes 'office' (I've seen this before).
'home'+'office'='HOME OFFICE'
Can you help me to learn more?
(Another definition for home office that I've seen is " Government department".)
