MARGARET Thatcher the worst Prime Minister of the last 100 years? I hardly think so (“Thatcher is voted the worst PM in century”, The Herald, October 19).

Rather, I agree with Lord Ashdown’s assessment: her success as one of our most enduring Prime Ministers of all time speaks for itself. And yes: she did leave Britain in a very much stronger place than she had found it.

She certainly merits the sobriquet The Iron Lady; but then again, she had to be.
