Jeremy Corbyn is a politician who serves as the MP for Islington North and formerly served as the leader of the Labour Party and the leader of the opposition for 3 years.
Corbyn is a controversial figure among Britain because he is quite far left for the modern Labour Party, which has recently become quite a centrist party. Corbyn, a democratic socialist, lead the Labour Party to the worst defeat it had ever seen since before WW2. After the 2019 election preceded, Corbyn resigned and was followed by Keir Starmer.
Used by member's of Britain's right wing Conservative Party as a last resort when they have no valid defense or comeback; especially during Prime Minister's Question Time.
Weak leader Rishi Sunak seems particularly fond of using it despite the argument being largely irrelevant now as Jeremy Corbyn no longer sits as a Labour party member.
Background:
The animosity towards Jeremy Corbyn stems from a successful smear campaign orchestrated by the Conservative party, especially during the 2019 election campaign where it was aided by the UK's overwhelmingly right wing media including the supposedly neutral BBC.
A crazy loving person that will never give up on you even when everything is going wrong. She's creative, talented, smart, artistic, funny, loving, and the most gorgeous girl you will ever see. She will be there for you when no one else is and can take a beating. She's a tough and stubborn ass but if you find a chick with the name Corynn grab her (unless it's mine leave her alone pls) because it will be the best decision you will ever make. Beware tho she's extremely gorgeous and has a great personality so every guy will chase after her.
