National Assembly for Wales
Under mixed member proportional representation
, a type of additional member system
forty of the AMs are elected from single-member constituencies on a plurality voting system
(or first past the post
) basis, the constituencies being equivalent to those used for the House of Commons
and twenty AMs are elected from regional closed lists
using an alternative party vote.
There are five regions: Mid and West Wales
, North Wales
, South Wales Central
, South Wales East
and South Wales West
(these are the same as the pre 1999 European Parliament constituencies for Wales), each of which returns four members.
The additional members produce a degree of proportionality within each region.
Whereas voters can choose any regional party list irrespective of their party vote in the constituency election, list AMs are not elected independently of the constituency element; rather, elected constituency AMs are deemed to be pre-elected list representatives for the purposes of calculating remainders in the d'Hondt method
Overall proportionality is limited by the low proportion of list members (33% of the Assembly compared with 43% in the Scottish Parliament
and 50% in the German Bundestag
) and the regionalisation of the list element.
Consequently, the Assembly as a whole has a greater degree of proportionality (based on proportions in the list elections) than the plurality voting system used for UK parliamentary elections, but still deviates somewhat from proportionality.
