Embrace special powers to oversee Yorkshire Water? (7)
I believe the answer is:
espouse
'embrace' is the definition.
(I know that embrace can be written as espouse)
'special powers to oversee yorkshire water?' is the wordplay.
'special powers' becomes 'ESP' (extra-sensory perception).
'to oversee' means one lot of letters go next to another (some letters go over and look down on others).
'yorkshire water?' becomes 'Ouse' (river in Yorkshire).
'esp'+'ouse'='ESPOUSE'
(Other definitions for espouse that I've seen before include "See opus to support a cause" , "Take in marriage" , "Champion or support, as with a cause" , "Adopt - give support to" , "Marry -- take on as a cause" .)
