I was asked how this differs from the Additional Member System used for the London and Welsh Assemblies. Firstly, it is very similar, and this is partly why I hope the system will be more acceptable to the establishment. The use of the d’Hondt system combined with regional top-up members is the same, and we know that it works in Britain.

However, the Regional Top-Up system proposed is simpler and doesn’t require voters to, confusingly, vote for a constituency MP and a party separately. The London and Welsh elections maintain the FPTP system for constituency elections, which means that voters are forced into voting for one of the main two local candidates, or waste their vote.

The AMS also still uses the dreaded party lists system which only ensures that the party favourites are elected, rather than the candidates most popular with the public.

So while the AMS is a definite improvement over the FPTP system, it also brings some distinct disadvantages with it which Regional Top-Up does not.
