 Originally both Members were chosen by the whole 'commons' of the borough until at least 1407, when Thomas Denton and John Tonge were stated to have been chosen 'per totam communitatem tocius burgi'.At some unknown date before the middle of the 15th century, however, the 'commons', lost power within the borough and were restricted to the election of just one of the Members, the other being chosen by the mayor and 24 jurats (or aldermen).This situation was reversed by the middle of the sixteenth century.
