Blaenau Gwent (Senedd constituency)

The constituency was created for the first election to the Assembly, in 1999, with the name and boundaries of the Blaenau Gwent Westminster constituency prior to the 2023 review of Westminster constituencies. The other seven constituencies of the South Wales East electoral region were Caerphilly, Islwyn, Merthyr Tydfil and Rhymney, Monmouth, Newport East, Newport West and Torfaen. ==History==

This seat had had large changes in percentages and swing. Labour have had large majorities but following the By-election in 2006 Blaenau Gwent People's Voice gained the seat, with the previous incumbent Peter Law's wife Trish Law taking the seat and holding it in the 2007 National Assembly for Wales election. The party did not stand in the 2011 election and Labour regained the seat with a very large majority. However, in the 2016 election this was slashed with Plaid Cymru increasing their vote from 5.4% to 36.6%. Blaenau Gwent People's Voice won the seat in the 2006 by-election and the 2007 election. ==Voting==

In general elections for the Senedd, each voter had two votes. The first vote was used to vote for a candidate to become the Member of the Senedd for the voter's constituency, elected by the first past the post system. The second vote was used to vote for a regional closed party list of candidates. Additional member seats were allocated from the lists by the d'Hondt method, with constituency results being taken into account in the allocation. ==Assembly members and Members of the Senedd==
