Sir, William Waldegrave (“Why I refused to sign the ‘no to AV’ letter”, Opinion, Mar 31) makes the point that under AV one’s vote remains of equal weight throughout. That is precisely the problem. You list the candidates in order of preference. Your first choice is presumably the person you wish to represent you. Your fifth choice is probably the person you regard as marginally less appalling than the candidate you put in sixth place. If those you listed as your first four preferences are eliminated, your vote for the fifth candidate counts the same as the vote of someone whose first choice has remained in the ballot. The votes are equal. The preferences of the voters are not.
