All elections to the UK Parliament are held under First Past the Post (FPTP). There was a referendum in 2011 regarding the electoral system, which returned a result in favour of keeping FPTP. Despite this, many in Scotland are unhappy with the system as they feel Scotland doesn't have a say in any plebiscite due to having a smaller population than England. A Scotland-only regional party, such as the SNP, cannot win a UK election, whereas an England-only regional party can. This has fuelled the Scottish independence movement as many think that is the only way for Scotland to make its own decisions.
