Tories Alan booted from Upper House (10)
I believe the answer is:
senatorial
'from upper house' is the definition.
(eg the senate is the US Congress' upper house)
'tories alan booted' is the wordplay.
'booted' is an anagram indicator (letters kicked or booted around).
'tories'+'alan'='toriesalan'
'toriesalan' is an anagram of 'SENATORIAL'.
(Other definitions for senatorial that I've seen before include "of the legislature" , "Like US upper assembly members" , "for a US politician?" .)
