David Cameron 11 May 2010 on the steps of no. 10.
"Nick Clegg and I are both political leaders who want to put aside party differences and work hard for the common good"
Communists? Of course not!
Of course, I can find a couple instances of anyone saying that phrase. I'm glad you can to.
I can, however, find thousands upon thousands of communists and Marxists emphasising the need to work together for the common good as it's a core party of their ideology.
