Cabinet of United KingdomThe Cabinet meets on aregular basis, usually weekly on a Thursday morning notionally to discuss the most important issues of government policy, and to make decisions. Despite the custom of meeting on a Thursday, after the appointment of Gordon Brown as Prime Minister the meeting day was switched to Tuesday.However, when David Cameron became prime minister, he held his cabinet meetings on Thursdays again. Theresa May switched the cabinet meetings back to Tuesday. The length of meetings varies according to the style of the Prime Minister and political conditions, but today meetings can be as short as 30 minutes, which suggests announcement or ratification of decisions taken in committee, by informal groups, or in bi-lateral discussions between the Prime Minister and individual colleagues, with discussion in Cabinet itself very limited. The Prime Minister normally has a weekly audience with the Queen thereafter.The Cabinet has numerous sub-committees which focus on particular policy areas, particularly ones which cut across several ministerial responsibilities, and therefore need coordination. These may be permanent committees or set up for a short duration to look at particular issues ("ad hoc committees"). Junior ministers are also often members of these committees, in addition to Secretaries of State. The transaction of government business through meetings of the Cabinet and its many committees is administered by a small secretariat within the Cabinet Office. Consequent Orders in Council are normally made by the Queen-in-Council with a quorum of the Privy Council, which meets monthly or ad hoc.The Institute for Government claims that the reduced number of full Cabinet meetings signify "that the role of Cabinet as a formal decision-making body has been in decline since the war."[citation needed] This view has been contradicted by Vernon Bogdanor, a British constitutional expert, who claims that "the Cabinet has, in fact, been strengthened by the decline in full meetings, as it allows more matters to be transferred to cabinet committees. Thus, business is done more efficiently."Most Prime Ministers have had a so-called "kitchen cabinet" consisting of their own trusted advisers who may be Cabinet members but are often non-cabinet trusted personal adviserson their own staff. In recent governments, generally from Margaret Thatcher, and especially in that of Tony Blair, it has been reported that many or even all major decisions have been made before cabinet meetings. This suggestion has been made by former ministers including Clare Short and Chris Smith, in the media, and was made clear in the Butler Review, where Blair's style of "sofa government" was censured. 18.Tony Blair’s political style is known as “sofa government”because____.
