Showering and seducing, leading with the other hand (9)
I believe the answer is:
lavishing
'showering' is the definition.
('lavish' can be a synonym of 'shower')
'seducing leading with the other hand' is the wordplay.
I cannot quite understand how this works, but
'leading' could be 'in' (in government) and 'in' is found in the answer.
'hand' could be 'l' (abbreviation for left, as in the left-hand side) and 'l' is present in the answer.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Another definition for lavishing that I've seen is " Spending recklessly".)
