The Additional Members System is a type of voting system. In the UK it is used to elect politicians to the Scottish Parliament and the Welsh Assembly. It’s often abbreviated to AMS.
It is considered a hybrid voting system because it is a mixture of First Past The Post (FPTP) and Proportional Representation.
In AMS voters have two votes. The first vote is for an individual candidate and the result is decided using a FPTP system.
The second vote is for a political party and some of the seats are awarded using a Party List system.
