OK this is factual and probably too boring as opposed to the easy "sound bite"

government by cabinet

The UK was, during the period 1939-45 governed by a cabinet led from 1940 onwards by Churchill as Prime Minister.

"In theory, Britain has a Cabinet government. This according to current constitutional theory, is where the Cabinet meets as a body to discuss issues relevant to the country. It discusses various points of view, weighs up arguments concerning whatever is being discussed and comes to a decision that is backed by the majority of the Cabinet. As such it becomes government policy, if supported in the House of Commons, and has the legitimacy of majority Cabinet support behind it. This means that decisions have collective responsibility behind them"

Churchill and his deputy Attlee and the other members of the war cabinet "won the war"
