Cabinet committees provide a framework for collective consideration of and decisions on major policies and issues of public interest. This enables decisions to be fully considered by those ministers most closely concerned in a way that the government as a whole can be accepted to accept responsibility for them. The prime minister chooses the people to be in the cabinets and also they affect how much power and what type of committee they are. Some PM's place a great deal of emphases on them, some don't. The prime minister controls what type of committees goes on and who is involved.
However cabinets exist because the prime minister cannot specialise in everything and so cabinets are they to inform the prime minister of all the details. Sometimes after this the prime minister will then make his decision, sometimes the PM will consult the members in the cabinet when making the decision. It is quite clear that the U. K has cabinet governments because the workload would be much too much for one leader to be able to cope with. Even if the PM wants to run the country without anyone else, there is simply no way he would be able to do this.
There are multiple decisions that have to be made and the cabinet ministers are the only people who have the skill and knowledge to be able to able to manage every matter that arises. It would be physically impossible for the PM to be able to manage every department in the government and to manage all the legalisation that has to go though the government each day. These responsibilities are handed out to the cabinet ministers to organise the government and meet with the PM to discuss all the biggest decisions that he has to make.
The other reason that proves that the government is run by the cabinet is that the cabinet has to represent everyone in the government. The cabinet is also here to represent everyone in the Labour party. This is because everyone in the labour party has different ideas and viewpoints, however they all need to support the leader because the leader has not been elected by anyone. The power of the elected party comes in the form of it's MP's it's Leader. Blair was never elected by the public so unless he can keep his party on his side, then he can be removed as leader.
If the cabinet did not exist then there would be no way to organise all the MP's and get anything done. The way the cabinet is done is so all the MP's can have a voice in the running of the Labour party. These views are then put forward in the meetings. The cabinet is not just a tool more helping the PM make decisions; it also enables the elected party to act as an entity and not hundreds of individual voices. The cabinet also keeps the power of the MP's to a minimum so that any leadership challenges are kept to a minimum. The formal powers of the PM are considerable.
Hmmm... The PM's powers are quite hard to judge because in the almighty Britain, we don't have a constitution outlining the powers such as the U. S constitution. This makes it quite hard to judge how much power the PM has and how much Power he is meant to have. Formally the powers are quite considerable because the only person whose powers even come close to that of the PM's are of course the beloved Queen's:). She can official impose limitations on certain parts of the PM's power and Parliament can impose limits on other parts of his power so that limits him a bit.
The Pm can for instance take us to war without Parliament but technically the Queen still has control over the troops and can stop this. However the problem we face here is even though she could technically do it, in most circumstances it would be a politically suicidal move. I've already said that I believe that the PM has quite considerable powers but I also believe that the Pm has also a large number of limitations placed on his power. Firstly, no one has actually elected the PM to run the country which I always find is rather glossed over sometimes.
People in this country elect local MP's who then represent them in parliament and the party who has the most representatives is the party in charge. They then can place an MP from that party to lead the party and indeed the nation. This is why I feel that perhaps the Pm has too much power but that's a different matter. The fact of the very large matter is that the party is the place with all the power and the PM should be just a spokesperson and a public front for that party. To pass most things you need the party to back it so saying that PM is the end all of power is going a bit far.
The party can remove the PM at any time they want and they don't have to consult the public about. This limits the power than a PM can have because a party can chuck him out if they don't like what he is doing. Also the Pm can not run this country on his own, every Pm needs to have advisors and I suspect that most of them will consult their advisors for most decisions they make. This again supports the fact that a PM is only a spokesperson for the party because the PM decides on things based on info from colleagues and they could be swaying him in one direction or another.
Also the PM does not have the power to seriously go against the will of the party because there is always someone to replace him and so each PM has to do things the party wants and what the party wants is to get re-elected so it is hard for the PM to do anything which the party is not in favour of (for this little exam just disregard the whole recent little Iraq thingy). His rivals in the party will have support from some of the Mp's so that is another way for parliament to stop the Pm from using his power since he himself cannot make laws, they all have to go though Parliament and then though Lords again.
In conclusion, the PM's powers are uncharted since we don't have anything exactly outlining everything, however even though the Pm has quite a lot of power as demonstrated he can't use that power for anything he wants since there are many road blocks that can limit and block his power. At the end of the day the Party with the biggest majority is the thing with the biggest power because that party as an entity can decide who will be prime minister and can also pass though any laws it wants though Parliament although the Lords will even still cap the parties power.
