Band claiming place in big story (6)
I believe the answer is:
splash
'big story' is the definition.
(a big story in a newspaper)
'band claiming place' is the wordplay.
'band' becomes 'sash' (a band of material).
'claiming' indicates putting letters inside.
'place' becomes 'pl' (abbreviation used in postal addresses).
'sash' enclosing 'pl' is 'SPLASH'.
'in' acts as a link.
(Other definitions for splash that I've seen before include "Small amount of soda water etc" , "Cause water to fly about in drops" , "Spend money freely, like loose water" , "Scatter water about" , "Spatter liquid about" .)
