Direction provided by leaders of Europe at summit talks (4)
I believe the answer is:
east
'direction' is the definition.
(compass direction)
'leaders of europe at summit talks' is the wordplay.
'leaders of' says to take the initial letters.
The first letters of 'europe at summit talks' is 'EAST'.
'provided by' is the link.
(Other definitions for east that I've seen before include "Chinese, perhaps" , "playing partner" , "Bidder after North (bridge)" , "One of four at table" , "E" .)
