Hey kiddo, have you ever heard of a parliament? It's a special group of people who make important decisions for their country or area.
Now, in Wales, they used to have something called the National Assembly. But some people thought that Wales should have its own parliament, just like Scotland and Northern Ireland.
So, the Parliament for Wales campaign is all about trying to convince the government that Wales should have its very own parliament. There are people who believe that having a parliament would help make better decisions that benefit the people of Wales.
The campaign involves lots of people coming together to show their support and share their opinions with the government. They might write letters, go to meetings, or even demonstrate to show how important this is to them.
Basically, it's all about trying to make sure that Wales gets the best possible representation and governance for its people.
