Sadly the only anecdote I can tell about her is a sad memory for me. A friend of mine worked as her researcher during the last Tory administration, but he developed schizophrenia. It was all very tragic. Last time I saw him he was severely disturbed, and I think he's now institutionalised. So, although she is the senior politician I had the closest real life link to, I know almost nothing real about her. The news of her death just brings my old friend to my mind.
To be positive - although Mo has gone, her life made a difference.
