=== Threshold ===
{{see also|Election threshold}}

As in many systems containing or based upon [[party-list]] representation, in order to be eligible for list seats in some AMS models, a party must earn at least a certain percentage of the total party vote, or no candidates will be elected from the party list. Candidates having won a constituency will still have won their seat. In almost all elections in the UK there are no thresholds except the "effective threshold" inherent in the regional structure. However the elections for the [[London Assembly]] have a threshold of 5% which has at times denied seats to the [[Christian Peoples Alliance]] (in [[2000 London Assembly election|the 2000 election]]), the [[British National Party]], [[Respect – The Unity Coalition]] (both in [[2004 London Assembly election|the 2004 election]]), and the [[Women's Equality Party]] (in [[2016 London Assembly election|the 2016 election]]).
