Central Anglo Saxon king? (5)

I believe the answer is:

midas

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

'king?' is the definition.
(mythical king)

'central anglo saxon' is the wordplay.
'central' becomes ''mid' (I've seen this in another clue).
'anglo saxon' becomes 'as' (this might be a standard abbreviation I've not previously seen).
'mid'+'as'='MIDAS'

Can you help me to learn more?

(Other definitions for midas that I've seen before include "Legendary king whose touch turned things to gold" , "my gift turned out a curse" , "Mythical king with golden touch" , "old king" , "Gold-creating king" .)

I've seen this clue in the Evening Standard.
