Boris welcoming newspaper spin? I see what you're saying (3-6)
I believe the answer is:
lip-reader
'i see what you're saying' is the definition.
(a lip reader literally sees what someone's saying)
'boris welcoming newspaper spin?' is the wordplay.
'boris' becomes 'leader' (Boris Johnson a political leader).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'newspaper' becomes 'i' (UK newspaper).
'spin?' becomes 'pr' (I've seen this in other clues).
'i'+'pr'='ipr'
'leader' placed around 'ipr' is 'LIP-READER'.
(Another definition for lip-reader that I've seen is " Person interpreting from mouth movements".)
