The Generalist

23d. Executive, conducive (11). M?N?S?E?I?L. Must be ministerial, which is just about reasonable for 'executive' but I can find no reason to parse it with 'conducive'. Can you?
Otherwise finished, after the usual struggle!

[Captain2]

Must admit I'm struggling to put 'executive' with 'conducive'.

How sure are you of the 'N'?

I'd have thought 'Magisterial' perhaps fits better?

[Calibax]

Chambers gives:minist\-erial adj of or relating to a minister or ministry (in any sense); on the government side; administrative; executive; instrumental; conducive.

[Captain2]

Thanks Calibax, I've never bought one of the 'posh' dictionaries that some crossword compilers refer to (perhaps I should!)

[Patsy33]

Minister+ IAL what do those letters stand for?..

[Aquagility]

So it does, and as Chambers is my bible I must accept it. Many thanks, Calibax.
And yes, Captain2, perhaps you should!
