// People have two votes - one for a constituency MSP, and another for a regional ballot.
There are 73 Constituency MSPs, each elected on a first-past-the-post system similar to the UK general election - the winner is the candidate who receives the most votes in each constituency.
In the regional ballot, people vote for a party. The parties are then allocated a number of MSPs depending on how many votes they receive, to make the overall result more proportional. //
