How to AV - You choose how many candidates to rank. Mark '1' for 1st choice, '2' for 2nd, etc. or 'X' for one choice only.
Counting AV - Add up 1st choices. If no-one has over 50%, reallocate choices of last placed candidate. Repeat until someone gets majority.
Why AV? - Ensures MP has 50% support. At present MP might need just 20% if 5 candidates standing, 10% if 10, and so on. Vote YES on May 5th.
