Veto organised in The House leads to accord? (8)
I believe the answer is:
dovetail
'accord?' is the definition.
(thesaurus)
'veto organised in the house' is the wordplay.
'organised' indicates an anagram.
'in the' indicates putting letters inside.
'house' becomes 'dail' (Dail is an example).
'veto' anagrammed gives 'ovet'.
'ovet' put into 'dail' is 'DOVETAIL'.
'leads to' acts as a link.
(Other definitions for dovetail that I've seen before include "Joint - fit neatly" , "Fit snugly" , "Joint of tenon and mortise" , "Joint with fan-shaped tenon" , "Fit closely together like white bird and appendage" .)
