British honours are awarded on merit, for exceptional achievement or service.
Anybody can recommend a British national for an honour, which consist of life peerages, knighthoods, appointments to the Order of the British Empire and gallantry awards to servicemen and women and civilians.
Nominations, sent either by government ministers or by members of the public, are divided into subject areas and assessed by eight committees comprising both senior civil servants and independent experts.
Their assessments are passed to a selection committee that produces the list that is submitted to the Queen through the prime minister.
The Queen formally approves the list of recipients. The honours are published in the official Crown newspaper, the London Gazette.
Private nominations, made by individuals or by representatives of organisations to the Cabinet Office, traditionally make up about a quarter of all recommendations.
Honorary awards for foreign nationals are recommended by the Secretary of State for Foreign and Commonwealth Affairs. Orders for chivalry are made after a personal decision by the Queen.
Life peerages are the only form of peerages regularly created by the Sovereign.
A life peer becomes a baron and sits in the House of Lords on conferment of peerage.
These are titles which they hold only during their lifetime and are not passed to their heirs.
The honour of knighthood comes from the days of medieval chivalry, as does the method used to confer the knighthood: the accolade, or the touch of a sword by the Sovereign.
Although Knights Bachelor do not comprise an order of chivalry, knighthood is a dignity which has its origins in Britain in Saxon times. They are styled "Sir" (except for clergymen who do not receive the accolade) and their wives "Lady".
Women receiving the honour are styled "Dame" but do not receive the accolade.
