Have you ever seen someone walking? Sometimes they take big steps, and sometimes they take tiny steps. Some people even hop or skip when they walk!
Well, in the world of politics, there was a man named Hugh Gaitskell who had ideas on how the government should run. He believed that the government should take small steps, like tiny steps when walking, instead of big ones, like huge steps when walking.
This idea of taking small, careful steps in government decisions is called "Gaitskellism." It means being very cautious and deliberate in the decisions made by the government. It's sort of like how you might take tiny steps when you're trying to be careful not to spill a glass of water.
Gaitskellism is important because it helps the government make thoughtful decisions that don't cause too much trouble. Just like taking tiny steps helps you walk carefully without tripping, Gaitskellism helps the government make small, thoughtful decisions that won't cause any problems down the road.
