SIR - Prime Minister’s question time on Wednesday was conducted by Deputy Prime Minister Nick Clegg and Deputy Shadow Leader of the opposition Harriet Harman.

I have noticed on the few occasions that this happens how Nick Clegg refuses to address Harriet Harman as the Shadow Deputy Leader and constantly refers to Ms Harman as she or her.

He displays a deeply patronising attitude and its time that Harriet Harman gave him the reply that my mother used to give to chauvinists who called her she and not her Christian name... ‘she is the cat’s mother’!
