'a dishy supporter more' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'recently entering the group' is the wordplay.
I cannot quite understand how this works, but
'recently' could be 'late' (I've seen this in other clues) and 'late' is present in the answer.
This explanation may well be incorrect...
