Delyn (Senedd constituency)

Delyn was a constituency of the Senedd. It elected one Member of the Senedd by the first past the post method of election. Also, however, it was one of nine constituencies in the North Wales electoral region, which elected four additional members, in addition to nine constituency members, to produce a degree of proportional representation for the region as a whole.

Boundaries

The constituency was created for the first election to the Assembly, in 1999, with the name and boundaries of the Delyn Westminster constituency. It was entirely within the preserved county of Clwyd.

As created in 1999, the North Wales region included the constituencies of Alyn and Deeside, Caernarfon, Clwyd West, Clwyd South, Conwy, Delyn, Vale of Clwyd, Wrexham and Ynys Môn. From the 2007 election the region included Aberconwy, Alyn and Deeside, Arfon, Clwyd South, Clwyd West, Delyn, Vale of Clwyd, Wrexham and Ynys Môn.

Voting

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