The cabinet: What is it and what does it do?
gets talked about a lot - whether it's drama at weekly meetings or big "reshuffles". Here's a very quick guide to what it is if you don't follow politics.
made up of about 20 people, usually MPs but sometimes members of the House of Lords. They are known as ministers, or in some cases, secretaries of state, depending on the job. 
For example, the finance minister - who goes by the title chancellor of the exchequer - decides how much money you will be taxed and where that money will be spent, while the home secretary looks after UK borders and policing. 
jobs are often given to the PM's friends and supporters. It's called a "reshuffle" when lots of the ministers are moved around, promoted or fired. Ministers can move between very different departments, so for instance they could move from transport to culture.
So the health secretary doesn't need to have worked as a doctor or nurse, for example. They take advice and decide what the department does. They take into account how much money needs to be spent, whether it's what the government promised they'd do, and how it affects voters.
Each department works with civil servants - people who aren't elected politicians or loyal to any political party. They work to make the government's plans happen.
meets weekly around a long table covered in deep green felt and there's a carved chair for every minister. The PM sits in the middle and where everyone else sits is said to indicate how important they are.
