Rising desperation shown by current partners at first (10)

'rising' is the definition.
(I know that insurgency is a type of rising)

'desperation shown by current partners at first' is the wordplay.
'desperation' becomes 'urgency' (desperate can mean urgent).
'shown by' is a charade indicator (letters next to each other).
'current' becomes 'I' (symbol for electric current).
'partners' becomes 'ns' (North and South are partners in the game bridge).
'at first' is a charade indicator (letters next to each other).
'i'+'ns' is 'ins'.
'urgency' put after 'ins' is 'INSURGENCY'.
