Staggering (7)

I think it could be either:

reeling

keeling

'staggering' is the definition.
('reel' can be a synonym of 'stagger')

This is the entire clue.

(Other definitions for reeling that I've seen before include "Swimming" , "Unable properly to control one's movements" , "may be off-balance" , "Punchy" , "groggy" .)

I've seen this clue in the Evening Standard, the Penny Press, The Guardian, the King Feature Syndicate, The Wall Street Journal and The Times.
