Who knows what's going on?
Voting is the only official way to have a say in what's happening, by choosing person who will represent you in parliament.
You can't vote unless you have registered at gov.uk/register-to-vote. You can register again if you don't know if you've done this already.
They Work For You is a site that clearly shows what's happening in the UK's parliaments, and you can use it to see how they voted, what they said in debates, their financial interests, and many other things. This is great to see if they practice what they preach (many don't!)
Use a service like FullFact.org who provide information so you can check the claims you hear from politicians and the media.
If an article bases its conclusions on a source or reference, check the reference material. It is common (yet bad practice) for newspapers (on all sides) to cherry-pick the data that confirms their belief, and ignore anything that opposes it.
Remember that a large number of news outlets surround fact with opinion. Treat headlines as you would treat a clickbaity YouTube video title. They're all designed to make you look, rather than to convey the most accurate summary of the facts..
Read articles, or speak to people with an alternative view to yours. Listen to what they have to say. Ask questions to try to understand their point of view and what is motivating it -- It's rarely as clear cut as a newspaper headline or a party stance. Expect to answer similar questions yourself.
This is not a suggestion to force your opinion on someone else: beware of "Sea Lioning". Free speech isn't a right to be listened to.
Write to your MP. They represent you. They can only represent you effectively if you let them know how you feel on an issue.
Politics Summary is intended to be non-partisan, to vent frustration with the current state of politics, and to provide information to help better educate people on all sides of the political spectrum.
