Perhaps May article on Salvation Army (7)

I believe the answer is:

theresa

'perhaps may' is the definition.
(Theresa May, former UK prime minister)

'article on salvation army' is the wordplay.
'article' becomes 'the' (the definite article).
'on' becomes 're' (regarding).
'salvation army' becomes 'SA' (abbreviation).
'the'+'re'+'sa'='THERESA'

(Other definitions for theresa that I've seen before include "Woman" , "Lisieux saint" , "Maria -, Austr. empress" , "Maria -, eighteenth century empress" , "Girl's name" .)

I've seen this clue in The Times.
