Clement Atlee would easily be included having not only been the Deputy Prime Minister to Winston Churchill during World War II he then went on to defeat Winston Churchill by a landslide in the '45 general election on a promise of creating for a post war future rather than revelling in a victorious past.
He was then the first Labour Prime Minister to serve a full parliament and command a majority.
And within 6 yeas his governments had created the NHS.
His government nationalised electricity, coal, aviation, etc etc. Which remained profitable industries even thought they introduced things like improved working conditions and a 5 day week for miners.
Despite the fact that post wartime the economy was destroyed he kept unemployment below 3% and built a million new homes.
Free secondary education became a right.
He also managed to lead a cabinet of strong individuals by acting as a chairman rather than as a president and the record of what he set out to achieve and what he then achieved has rarely if ever been matched.
Incidentally Churchill always denied saying the modesty quote having been pleased with his wartime service.
Alternative quote: Christopher Soames, Britain's Ambassador to France during the government of Edward Heath - and later a cabinet minister under Margaret Thatcher - remarked that "Mrs. Thatcher was not really running a team. Every time you have a Prime Minister who wants to make all the decisions, it mainly leads to bad results. Attlee didn't. That's why he was so damn good."
And even Mrs Thatcher said "Of Clement Attlee, however, I was an admirer. He was a serious man and a patriot. Quite contrary to the general tendency of politicians in the 1990s, he was all substance and no show".
But my favourite quote about Clement Atlee, not a fan of small talk, was the person who was sat next to him at a function and said "Someone bet me I wouldn't be able to get three words out of you all night" he was quiet for a long time before eventually saying "you lose"
Finally if my ramblings have failed to convert you in 2004 and 2010 University of Leeds conducted a poll of over 200 academics who specialised in 20th century British politics or history.
Both times topping the poll ahead of Thatcher, Churchill, Blair and Lloyd George was....
Modest Mr Atlee
