Information: - The Prime Minister of the United Kingdom 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, most of whom 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 office is one of the Great Offices of State. The , Theresa May, leader of the Conservative Party, was appointed by the Queen on 13 July 2016. - Sir William James Lynton Blair ( born 31 March 1950 ) , styled The Hon. Mr Justice Blair , is a British judge . He was previously a Queen 's Counsel , specialising in domestic and international banking and finance law . His younger brother is the former British Prime Minister Tony Blair . - A court is a tribunal, often as a government institution, with the authority to adjudicate legal disputes between parties and carry out the administration of justice in civil, criminal, and administrative matters in accordance with the rule of law. In both common law and civil law legal systems, courts are the central means for dispute resolution, and it is generally understood that all persons have an ability to bring their claims before a court. Similarly, the rights of those accused of a crime include the right to present a defense before a court. - The Crown is the state in all its aspects within the jurisprudence of the Commonwealth realms and their sub-divisions (such as Crown dependencies, provinces or states), although the term is not only a metonym for "the State". The Crown is a corporation sole that represents the legal embodiment of executive, legislative, and judicial governance in the monarchy of each country. These monarchies are united by the personal union of their monarch, but they are separate as states. The concept of the Crown developed first in the Kingdom of England as a separation of the literal crown and property of the nation state from the person and personal property of the monarch. The concept spread through English and later British colonisation and is now rooted in the legal lexicon of the other 15 independent realms and the three Crown dependencies. In this context it should not be confused with any physical crown, such as those of the British royal regalia. - The title of Senior Counsel or State Counsel (post-nominal letters: SC) is given to a senior lawyer in some countries that were formerly part of the British Empire. "Senior Counsel" is used in current or former Commonwealth countries or jurisdictions that have chosen to change the title "Queen's Counsel" to a name without monarchical connotations, sometimes (but not always) because the British monarch is no longer head of state, such that reference to the Queen is no longer appropriate. Examples of jurisdictions which have made the change because of the latter reason include Mauritius, Zambia, India, Hong Kong, the Republic of Ireland, South Africa, Kenya, Malawi, Singapore, Guyana and Trinidad and Tobago. Just as a junior counsel is "called to the [Outer] Bar", a Senior Counsel is, in some jurisdictions, said to be "called to the Inner Bar". Senior Counsel may informally style themselves as "silks", like their British counterparts. This is the case in Ireland, Australia, Hong Kong and South Africa. - Anthony Charles Lynton Blair, (born 6 May 1953), commonly called Tony Blair, is a British politician who served as the Prime Minister of the United Kingdom from 1997 to 2007 and the Leader of the Labour Party from 1994 to 2007. Together with President George W. Bush in 2003, he initiated the Iraq War with the invasion of Iraq, an act which remains highly controversial. - A Queen's Counsel (postnominal QC), or King's Counsel (postnominal KC) during the reign of a king, is an eminent lawyer (mostly barristers) who is appointed by the Queen to be one of "Her Majesty's Counsel learned in the law." The term is also recognised as an honorific. Membership exists in various Commonwealth jurisdictions around the world, while in some other jurisdictions the name has been replaced by one without monarchical connotations, such as "Senior Counsel" or "Senior Advocate". Queen's Counsel is a status, conferred by the Crown, that is recognised by courts. Members have the privilege of sitting within the Bar of court.
