Charge leaders of Albion staging social activities in lockdown (6)
I believe the answer is:
assail
'charge' is the definition.
(I know that charge is a more specific form of the action rush)
'leaders of albion staging social activities in lockdown' is the wordplay.
'leaders of' indicates taking the first letters.
The initial letters of 'albion staging social activities in lockdown' is 'ASSAIL'.
(Other definitions for assail that I've seen before include "Launch an attack" , "Attack, lash out" , "Maybe mug" , "storm" , "Trouble" .)
