The fathers of Scottish devolution came up with a system so complicated as to confuse even the most passionate observer and student of the political scene north of the border. There were three guiding principles
• To preserve the best of the Westminster “first past the post” system, which provides a clear result and a named MP for a constituency
• To ensure that those who voted for a party other than the winning party still had a chance or representation in the parliament (there is a second vote for list MPs in each constituency)
• To make an overall majority government a rare occurrence – and it is this requirement that has caused the hideous complication!
