The Cabinet is the group of senior government ministers who are responsible for implementing the government's manifesto pledges.
Cabinet meetings are chaired by the Prime Minister at Downing Street once a week.
The Cabinet is bound by collective responsibility, which means that all its members must abide by and defend the decisions it takes.
Cabinet ministers are appointed by the Prime Minister and chosen from Labour's MPs or peers.
