Thatcher got into power in 1979. Tories in power until Blair. Blair was closer to being a Tory than traditional labour. Hence the name new labour. Since he and brown left, been tories again.
So we’ve went from Tory to Tory-lite since 1979. 42 years.
Arguing semantics opposed to my overall point is kinda what the tories are renowned for. Bravo.
