Following on, batting during day (7)
I believe the answer is:
retinue
'following' is the definition.
(I've seen this in another clue)
'on batting during day' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'batting' becomes 'in' (cricket term).
'during' indicates putting letters inside.
'day' becomes 'tue' (abbreviation for Tuesday).
'in' put within 'tue' is 'tinue'.
're'+'tinue'='RETINUE'
(Other definitions for retinue that I've seen before include "Group of attendants for VIP" , "Train, escort" , "Group around VIP" , "Entourage, followers" , "Band of attendants" .)
