Popular elsewhere, to some extent (2,1,3)

I believe the answer is:

in a way

'to some extent' is the definition.
(I've seen this before)

'popular elsewhere' is the wordplay.
'popular' becomes 'in'.
'elsewhere' becomes 'away' (I've seen this before).
'in'+'away'='IN A WAY'

(Other definitions for in a way that I've seen before include "as one might see it" , "Kind of" , "To a certain extent" , "Sort of, to a limited extent" , "In some respects, to a limited extent" .)

I've seen this clue in The Telegraph.
