Each voter has two votes, one for constituency
representative and one for a regional party list
A proportion of seats are filled by FPTP. The
remaining seats are filled using 'closed'
party list system. Tops up
Where it is used
The Welsh assembly
Advantages
The mixed characteristics of this system balances the need for
constituency representation against the need for electoral fairness
Although the system is broadly proportional in terms of
it outcomes, it keeps alive the possibility of single party
government
It allows voters to make wider and more considered choices. For
example they can vote for different parties in the constituency and
list elections
Disadvantage
The retention of single member constituencies reduces the
likelihood of high levels of proportionality
The system creates confusion by having two
classes of representation
Constituency representation will be less effective than it is FPTP
because of the larger size of constituencies and because a
proportion have no constituency
