For LuckyGirl - your "I selected a particular item from the article as it reflected a particular concern I had with it and was interested to see what others thought" - is at best shortsighted. Of course lots of people wouldn't go and check all the precise wording!
Thatcher made a mass of mistakes, ("Poll Tax" anyone?!) and of course decimated all the heavy manufacturing in the Midlands and North -- though economists would argue that under the union domination that had preceded her, productivity was so low that they didn't actually manufacture that much by that stage.
She also designed the Rail privatisation model - criticised at the time but implemented anyway by Major (who still pops up to lecture people) - and we know how well that went, costing us all masses of funding with huge fares and a crackpot ticketing system ("Yes, you might save £3.75 if you get 7 tickets for your journey. You might also get to Edinburgh from London for £24 if you find the one ticket on our system at that price and travel at 3am one day 5 months away").
And whilst she is STILL FONDLY REMEMBERED by all those (including in the affected regions) who took advantage of her policy to sell off council houses, she did of course forget to do anything about replacing all that lost stock, an error unaddressed by Bliar, Brown, Cameron, or the sad set of inadequates we've had as PM since.
The power of the press re Politics is greatly overestimated. Very few potential Labour voters would be reading the Telegraph anyway. Not many Tories will be reading the Mirror to get upset by whatever revelation they might print about BoJo's excesses. Etc.
As for ALL THOSE saying "surely we could have a PM with strong principles", er, look back at Thatcher?!! Or "why do politicos sway in the breeze, appealing to this or that group" - it's a feature, comes with their territory.
