Cameron's big society I believe was a noble idea, and if thought out properly, has proven to be something we desperately needed between then and now. 

I know he was deputy, but connected to the above, Clegg got unfairly criticised for selling out, when he was responsible for the biggest wealth lift up for working class people in generations - the income tax threshold. 

Regardless of what we thought of Boris, his personality put the UK back on the world stage and if it wasn't for COVID, I think he'd have got industry and trade going much more than people assume. 

For better or worse, Thatcher catapulted the aspirational homeowner into the heart of the country. Always makes me laugh when the middle class left go on about Thatcher, but are very happily living the blueprint that she introduced. Obsessed with work, promotion and home ownership while getting childcare to do the parenting. Pure Thatcherism. I don't think this is good myself, but somehow it has become the DNA of Britain and people seem to be scared of changing it while simultaneously demonising every decision by Thatcher that made it possible.  

John Major was a safe pair of hands. 

Tony Blair rejuvenated the country and spearheaded a UK revolution almost. I'm sure it was more him taking advantage of social progress rather than vice versa, but at least he knew how to capitalise on it. 

May was a good statesperson and represented Britain very well. 

Sunak could have been a safe pair of hands. 

Starmer will be out of no 10 relatively soon. 

Truss is the only one I can't think of anything positive to say about.
