I'm a little stuck... Click here to teach me more about this clue!

'turn round' is the definition.

I cannot understand how the rest of the clue works.

(Other definitions for spin that I've seen before include "cycle ride" , "Jaunt" , "Rotate, twirl" , "Weasel words" , "present information favourably" .)

I've seen this clue in the Evening Standard.
