Harriet Harman says Thatcher's government was best...

After all, that's the only obvious conclusion one can draw from her statements to the Times:

I think a balanced team of men and women makes better decisions.

and when she "insisted that men should not be left to run things on their own."

The only 20th century premiership that had a leader/deputy leader pairing of a woman and a man was of course the Thatcher premiership.

I'm not unsympathetic to the notion it was successful, I just wasn't expecting the endorsement of the deputy leader of the Labour Party.
