Old order from EEC remaining uncertain (6,6)

I believe the answer is:

ancien regime

'old order' is the definition.
(term for pre-Revolutionary France)

'eec remaining uncertain' is the wordplay.
'uncertain' is an anagram indicator.
'eec'+'remaining'='eecremaining'
'eecremaining' with letters rearranged gives 'ANCIEN REGIME'.

'from' acts as a link.

I've seen this clue in The Times.
