Letter to the editor: On the assumption some tunnel-vision Conservatives will object to Mr Henderson’s criticism of Lady Thatcher (Celebrate Thatcher’s Day By Remembering Her ‘Positive’ Contributions, News Shopper, May 1) I would like to offer him my support.

Though I applauded her defeat of the aggressively militant Arthur Scargill, I criticise her refusal to allow unions at GCHQ Cheltenham, on the grounds we could not expose national security to striking unions, even after the union offered a legally binding agreement not to take strike action.

The facts changed, her reason was now invalid, but “this Lady is not for turning” seemed to regard rejecting this as something to be proud of.

Wise people say when the facts change, they change their opinion, but not her.

I also criticise her failure to appoint a woman to her cabinet and wonder as to her motivation.

We also have the problem of funding national pensions, after her sale of the family silver which would have contributed.

Surely there was a better way of improving management of public utilities than selling them, ultimately to foreign buyers in the main, who now profit from their ownership.

Like most prime ministers, Lady Thatcher did some things right and some things wrong.

Her death is not a reason to deny the latter, while it remains appropriate to acknowledge the former.
