(1) If the presiding officer is satisfied that owing to the blindness or other physical infirmities an elector is unable to recognise the symbol on the balloting unit of the voting machine or unable to record his or her vote by pressing the appropriate button thereon without assistance, the presiding officer shall permit the elector to take with him or her a companion of his not less than eighteen years of age to the voting compartment for recording the vote on his behalf and in accordance with his wishes:
Provided that no person shall be permitted to act as the companion of more than one elector at any polling station on the same day:
Provided further that before any person is permitted to act as the companion of an elector on any day under this rule that person shall be required to declare that he will keep secret the vote recorded by him on behalf of the elector and that he has not already acted as the companion of any other elector at any other polling station on that day.
(2) The presiding officer shall keep a record in Form 26 of all cases under this rule.
