Why are there two votes?

Members of the Scottish Parliament are elected using the Additional Member System (AMS). This is a form of proportional representation. This video explains how it works. The formula mentioned in the video is called the D'Hondt method. This allocates additional seats to political parties or independent candidates according to the number of regional votes cast for that party or independent candidate, divided by the number of seats (constituency and regional) already gained in that region, plus one.
