Dd, aged 9 has come home from school saying that her teacher used their Geography lesson to lecture the children on how wonderful Thatcher was and how nearly everyone in the UK thought she was doing the right thing. 
I think it is wrong for a teacher to express their political opinions to a class they teach, and particularly to misrepresent the truth about someone who divided opinion so much in the Uk, and make her out to be some kind of saviour.
This teacher has always seemed great to me in the past - what was she thinking??
