Bless the Tories and European Commission value (10)
I believe the answer is:
consecrate
'bless' is the definition.
('consecrate' can be a synonym of 'bless')
'the tories and european commission value' is the wordplay.
'the tories' becomes 'cons' (I've seen this in other clues).
'and' says to put letters next to each other.
'european commission' becomes 'ec'.
'value' becomes 'rate' ('rate' can be a synonym of 'value').
'cons'+'ec'+'rate'='CONSECRATE'
(Other definitions for consecrate that I've seen before include "Make holy" , "Sanctify" , "giving cause to be respected" , "Bless" , "Make 18 [SACRED]" .)
