The Honourable and Right Honourable in British public life

What British award or office entitles someone to be called the Honourable or Right Honourable?

Several conventions use Honourable, while Privy Council membership is a principal route to Right Honourable.

No single award accounts for every use of the Honourable. Parliamentary and peerage conventions provide several forms, while clergy, military officers, and barristers can acquire qualified usages in formal settings. Membership of the Privy Council is an important route to the style Right Honourable. British titles preserve institutional distinctions that cannot be reduced to one rank or decoration.
