Prime minister

A prime minister is the most senior minister of cabinet in the executive branch of government, often in a parliamentary or semi-presidential system. In many systems, the prime minister selects and may dismiss other members of the cabinet, and allocates posts to members within the government. In most systems, the prime minister is the presiding member and chairman of the cabinet. In a minority of systems, notably in semi-presidential systems of government, a prime minister is the official who is appointed to manage the civil service and execute the directives of the head of state.

In parliamentary systems fashioned after the Westminster system, the prime minister is the presiding and actual head of government and head of the executive branch. In such systems, the head of state or the head of state's official representative (i.e. the monarch, president, or governor-general) usually holds a largely ceremonial position, although often with reserve powers.

The prime minister is often, but not always, a member of parliament and is expected with other ministers to ensure the passage of bills through the legislature. In some monarchies the monarch may also exercise executive powers (known as the royal prerogative) that are constitutionally vested in the crown and may be exercised without the approval of parliament.

Theresa May

Theresa Mary May (née Brasier; born 1 October 1956) is a British Conservative Party politician who has been Home Secretary of the UK since 2010.

May was first elected to Parliament in 1997 as the Member of Parliament for Maidenhead. She went on to be appointed Chairman of the Conservative Party and was sworn of Her Majesty's Most Honourable Privy Council in 2002.

She served in a number of roles in the Shadow Cabinets of William Hague, Iain Duncan Smith, Michael Howard and David Cameron, including Shadow Leader of the House of Commons and Shadow Work and Pensions Secretary.

When David Cameron became Prime Minister in 2010, May was appointed Home Secretary and Minister for Women and Equalities, giving up the latter role in 2012.

Early life, education and career

Born on 1 October 1956 at Eastbourne, Sussex, May is the daughter of Hubert Brasier, an Anglican clergyman and Zaidee (née Barnes) Brasier.

May was educated at primary and grammar schools in the State sector, as well as a short spell at an independent Catholic school. She initially attended Heythrop Primary School, Oxfordshire, followed by St. Juliana's Convent School for Girls, a Roman Catholic independent school in Begbroke, which closed in 1984. At the age of 13, she won a place at the former Holton Park Girls' Grammar School in Wheatley, Oxfordshire. In 1971, the school was abolished and became the site of the new Wheatley Park Comprehensive School during her time as a pupil. May then went to the University of Oxford where she read Geography at St Hugh's College, graduating with a BA (Hons) degree in 1977.

Prime Minister of the United Kingdom

The Prime Minister of the United Kingdom of Great Britain and Northern Ireland is the head of Her Majesty's Government in the United Kingdom. The Prime Minister (informal abbreviation: PM) and Cabinet (consisting of all the most senior ministers, who are government department heads) are collectively accountable for their policies and actions to the Monarch, to Parliament, to their political party and ultimately to the electorate. The current Prime Minister, David Cameron, leader of the Conservative Party, was appointed by the Queen on 11 May 2010.

The office is not established by any constitution or law but exists only by long-established convention, which stipulates that the monarch must appoint as prime minister the person most likely to command the confidence of the House of Commons; this individual is typically the leader of the political party or coalition of parties that holds the largest number of seats in that chamber. The position of Prime Minister was not created; it evolved slowly and erratically over three hundred years due to numerous acts of Parliament, political developments, and accidents of history. The office is therefore best understood from a historical perspective. The origins of the position are found in constitutional changes that occurred during the Revolutionary Settlement (1688–1720) and the resulting shift of political power from the Sovereign to Parliament. Although the Sovereign was not stripped of the ancient prerogative powers and legally remained the head of government, politically it gradually became necessary for him or her to govern through a Prime Minister who could command a majority in Parliament.

Prime number

A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 5 is prime because 1 and 5 are its only positive integer factors, whereas 6 is composite because it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 can be expressed as a product of primes that is unique up to ordering. The uniqueness in this theorem requires excluding 1 as a prime because one can include arbitrarily many instances of 1 in any factorization, e.g., 3, 1 · 3, 1 · 1 · 3, etc. are all valid factorizations of 3.

The property of being prime (or not) is called primality. A simple but slow method of verifying the primality of a given number n is known as trial division. It consists of testing whether n is a multiple of any integer between 2 and . Algorithms much more efficient than trial division have been devised to test the primality of large numbers. These include the Miller–Rabin primality test, which is fast but has a small probability of error, and the AKS primality test, which always produces the correct answer in polynomial time but is too slow to be practical. Particularly fast methods are available for numbers of special forms, such as Mersenne numbers. As of January 2016, the largest known prime number has 22,338,618 decimal digits.
