UK Election For Newbies

There are just over 5 million 18 to 23 year olds in the UK which means 5 million people who were not able to vote at the last General Election in 2019 so all this stuff going on may be a bit tricky to understand so here's a little guide to understanding the UK General Election.
What is a general election for? It is not to pick a Prime Minister as you may think, that is just a consequence of whoever gets the most votes so you can't vote for who you want to be Prime Minister, you can vote for your local MP who will represent your areas or constituency which is one of 650.
Whichever Party wins the most constituencies, get to make up the Government and whoever is leader of that party becomes the Prime Minister.
Our system is called the First Past The Post System which means whichever party gets to 326 seats and therefore cannot be beaten and can form the next government.
To be able to vote you must be over 18, must be registered to vote in your constituency, must be either a British citizen, a qualifying Commonwealth citizen or a citizen of the Irish Republic and must not be a convicted prisoner or in a mental hospital.
To actually vote you take your poll card and photo ID to a polling station on 4th July between 7am and 10pm and you will be handed a ballot paper with the list of candidates and their parties and you put a cross next to the MP you want to vote for and slip it into the ballot box.
Voting closes at 10pm and there will be an exit poll which is basically a survey of people being asked who they voted for and they are generally a very good indicator of what to expect because by the time the ballot boxes are collected and the votes counted it is generally after midnight and goes on through the night with the the final results coming in by late morning.
A hung parliament happens when no party has the 326 seats needed for the majority so parties come to an arrangement to get together to make the 326 between them and then the parties rule together as a coalition government as the Conservatives and Liberal Democrats did in 2010.
If the ruling party win then they carry on but if they lose then the prime minister resigns and the King will invite the leader of the party that has won the election to form a government and move their furniture in 10 Downing Street.
Five years later we get to do it all over again.
