The Cabinet is a group of about 20 senior Ministers who meet every Tuesday. This is more often if there is a pressing issue to discuss.
The Prime Minister decides who will be in the Cabinet. But, it is accepted that all the Ministers who run Departments are Cabinet Members, as is the Chief Whip and the Leader of the House, the Minister who looks after Government Business in the Commons. The Chair of the Conservative or Labour Party may also be a member.
The Prime Minister and the Cabinet Secretary, who is the most senior civil servant, draw up the Agenda.
The Cabinet Office, staffed by civil servants, prepares papers for the Cabinet. It will coordinate issues that cut across Government Departments and looks to see that Cabinet decisions are carried out.
Cabinet meetings will discuss:-
As well as the weekly meetings, Cabinet is best thought of as a system. There are a range of meetings between the Prime Minister and one or two Ministers.
Ministers will keep in touch with each other over issues and meet if necessary.
Officials at No 10 and the Cabinet Office will be in contact with Cabinet Ministers to make sure that there is overall agreement on a course of action that might be controversial.
