Article 6
The whole number of councillors shall be elected at the ordinary elections of councillors in 1991.
Of the councillors elected in 1991 for any ward of the Borough —
one third shall retire in 1992 being, subject to paragraphs (3) and (4) below, the councillor elected by the smallest number of votes;
one third shall retire in 1994 being, subject as aforesaid, the councillor elected by the next smallest number of votes;
the remaining councillor shall retire in 1995.
In the case of an equality of votes between any persons elected which makes it uncertain which of them is to retire in any such year, the person to retire in that year shall be determined by lot.
If an election of councillors for any ward is not contested, the person to retire in each such year shall be determined by lot.
Where under this article any question is to be determined by lot, the lot shall be drawn at the next practicable meeting of the council after the question has arisen, and the drawing shall be conducted under the direction of the person presiding at the meeting.
