emission

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

'the issue' is the definition.
(I've seen this before)

'head of ethiopian legation' is the wordplay.
'head of' indicates taking the first letters.
'legation' becomes 'mission' (legation can mean a diplomatic mission).
The first letter of 'ethiopian' is 'e'.
'e'+'mission'='EMISSION'

'raises' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.

Can you help me to learn more?
