Ok kiddo, let me explain something called the House of Lords. It's a group in the UK that helps make laws but they're a little different than the other group, called the House of Commons. The members of the House of Commons are elected by the people and they represent different areas of the UK. But the members of the House of Lords aren't elected, they're either given the job because of their family or they're appointed by the prime minister.
Now, some people think that's not fair, that everyone should have a chance to be in the House of Lords, not just people with special connections. That's why they want to change it, or reform it, so that more people can be in the House of Lords and it will better represent everyone in the UK.
Some people think the House of Lords should be completely replaced with a new group that's elected by the people, just like the House of Commons. Others think it should stay the same but have more people from different careers, like doctors or scientists, be members. There are lots of ideas about how to reform the House of Lords and make it better, so we'll just have to wait and see what happens.
