Leaflet about United Kingdom being more fortunate (7)

I believe the answer is:

flukier

'more fortunate' is the definition.
(fluky means lucky or fortunate)

'leaflet about united kingdom' is the wordplay.
'leaflet' becomes 'flier' (I've seen this in another clue).
'about' indicates putting letters inside.
'united kingdom' becomes 'UK' (synonyms).
'flier' enclosing 'uk' is 'FLUKIER'.

'being' is the link.

I've seen this clue in The Guardian.
