I’d forgotten about the Thatcher portrait. That really pissed me off - and I’m as lefty as they come and grew up under Thatcher’s government; I’m fully aware of the harms she did. But show some respect for no. 10 and the people who have democratically taken their place there - whether you agree with them or not, whether history judged them well or not, whether they were a terrible leader or not - especially before you’ve even had a go at making a good fist of it yourself.
A portrait of thatcher, and even Liz truss if there is one (though less of a democratic choice), is a record of previous inhabitants and should be there to remind you to try to do a good job and understand the historical significance of that place which you are just passing through. Removing portraits like that has a very unpleasant bad taste to it that brings to mind some of the worst regimes in history. It’s arrogant and made me really question his mindset.
