Thatcher's revolting for jailing opposition leader and the Queen (6)
I believe the answer is:
roofer
'thatcher's' is the definition.
(a roofer might thatch roofs)
'jailing opposition leader and the queen' is the wordplay.
'jailing opposition' becomes 'roo' (I am not sure about this - if you are sure you should believe this answer much more).
'leader' becomes 'f' (I have seen 'German leader ' mean 'f' so perhaps 'leader' could also mean 'f').
'and' means one lot of letters go next to another.
'the queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'roo'+'f'+'er'='ROOFER'
'revolting for' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
(Other definitions for roofer that I've seen before include "One putting top on building" , "High-level building worker" , "One works on the top of a house" , "eg Thatcher" , "Person working on top of a house" .)
