brief explanation on politics please Watch
As for Brexit, there are clearly different viewpoints, false information and bias. I like The Week as it gives a synopsis of the different sides (The Times, The Telegraph, The Guardian and international press views). It's subscription based though but I think you can do a trial --- https://www.theweek.co.uk/brexit-0
Finally, party politics - I haven't seen any summary guides but Tutor2u shares ALevel notes on the core political ideologies but it may be overly detailed for your needs:
- Conservatism - https://www.tutor2u.net/politics/col...s/conservatism
- Socialism - https://www.tutor2u.net/politics/col...gies-socialism
- Liberalism - https://www.tutor2u.net/politics/collections/liberalism
The different political parties are all "broad churches" - ie each party membership is wide and members have different views on their core ideologies which can create tensions within each party. Here is a 20 mins video on UK politics which explains the different parties, their typical positions (left wing / right wing / centrist) and how the parties can move further to the right or left depending on the leader's viewpoint.
Hope that helps.
PS: Crash Course has a great course on US Politics but I don't think there is one on UK Politics.
