Press in rapture over newspaper leaders (4)
I believe the answer is:
iron
'press' is the definition.
(ironing is a kind of pressing)
'in rapture over newspaper leaders' is the wordplay.
'leaders' says to take the initial letters.
The first letters of 'in rapture over newspaper' is 'IRON'.
(Other definitions for iron that I've seen before include "uncompromising" , "Metal (that may be pumped?)" , "Metal - press" , "Very robust" , "Former dividing line across Europe" .)
