The ways in which the cinque ports differed from parliamentary boroughs included:
Whereas the MPs from a borough were called "burgesses" (or "citizens" in a borough with city status) those from a cinque port were called barons.[2] Barons had higher precedence than other MPs: whereas burgesses and citizens were called to a new Parliament on the first day, and knights of the shire (elected for county constituencies) on the second day, the barons were summoned to the Commons on the third day, along with the peers to the House of Lords.[3]
Until the Glorious Revolution, the Lord Warden claimed the right to nominate one of the two members returned by each cinque port.[4] This right was contested by the corporations. In the 1620s, Sandwich and Dover burgesses objected to Lord Zouche's nominees; the Sandwich objection was rejected, while that of Dover was accepted and the MPs unseated.[5] The right was definitively extinguished by the Parliamentary Elections Act 1689 (2 Will. & Mary c.7).[4][6]
