- Additional member system
- The additional member system is a hybrid of mixed system, combining elements of FPTP and proportional representation

- Used in the Scottish parliament, Welsh assembly, and greater London assembly
- The second is for a party list and uses multi-member regional constituencie introducing an element of proportional representation
- There are fewer list members than constituency representatives, and so they are known as additional or top up members.
- Single transferable vote
- An electoral system that allows voters to rank their preferences in numerical order.
- In order to win a seat, a candidate must obtain a quota. After the votes are cast, those candidates with the least votes are eliminated and their votes are transferred.
- Those candidates with excess votes above the quota also have their votes transferred
- Used in N.Ireland assembly, Scottish council elections
- The results are calculated using a complex counting process that takes into account voters second preference. If a candidate reaches the quota on the first round of counting, they are elected. If no one attains the quota, the least popular candidate is eliminated and their votes are transferred, cont until all the seats are filled
- Supplementary vote
- A majoritarian electoral system that gives the voter two choices. If one candidate obtains more than 50 percent on the first vote, they are elected.
- If no candidate attains this, all but the top two candidates remain. The second preference choices are added to produce a winner
