The british left can't accept that Blair was very popular, and very good at progressive policies. The left seem to want progess but only it comes through state ownership. Just look at what he achieved.
-Introduced the minimum wage, that's right before Blair it didn't exist
-Doubled Maternity leave, and introduced Paternity leave
-Intervened in Sierra Leon and Kosovo
-Finished the Northern Ireland peace process
-Lead EU reform, whilst keeping the UK out the Euro
-Introduced tough and neccessary anti-terror laws
-Reformed the house of lords, and made it more democratic
-Massive investment in the NHS and Schools
Britain was crap in 1997 after 18 years of tory rule. TB sorted it out. Perhaps I'm bias though
A lot of that isn't "progressive" in the slightest.
