Old president in uniform following ceremony I perform (8)

I believe the answer is:

pompidou

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

'old president' is the definition.
'pompidou' can be an answer for 'president' (French president Georges Pompidou). I'm not certain of the 'old' bit.

'uniform following ceremony i perform' is the wordplay.
'uniform' becomes 'U' (phonetic alphabet: alpha, bravo, charlie etc.).
'following' is a charade indicator (letters next to each other).
'ceremony' becomes 'pomp' (I've seen this in another clue).
'perform' becomes 'do' (both can mean complete an action).
'pomp'+'i'+'do'='pompido'
'u' after 'pompido' is 'POMPIDOU'.

'in' is the link.

Can you help me to learn more?

(Other definitions for pompidou that I've seen before include "Once leading Frenchman" , "Paris arts centre name" , "statesman" .)

I've seen this clue in The Times.
