# Cardiff South and Penarth (Senedd constituency)

Cardiff South and Penarth (Welsh: De Caerdydd a Phenarth) is a constituency of the Senedd. It elects one Member of the Senedd by the first past the post electoral system. It is typically a safe Labour seat.

## Constituency profile and voting

The constituency was created for the first election to the Assembly, in 1999, with the name and boundaries of the Cardiff South and Penarth Westminster constituency. It is entirely within the preserved county of South Glamorgan. The only major boundary changes that have occurred in recent years is the inclusion of the ward of Sully into the constituency for the 2007 National Assembly for Wales election.
Cardiff South and Penarth is part of the South Wales Central electoral region. As one of the eight constituencies in South Wales Central, it, along with the other constituencies in the region, elect four additional members. The other seven constituencies of the region are Cardiff Central, Cardiff North, Cardiff West, Cynon Valley, Pontypridd, Rhondda and Vale of Glamorgan.
The use of the Additional Member System means that each voter has two votes. The first vote is for a candidate to become the Member of the Senedd for the voter's constituency, elected under the first past the post system. The second vote is used to vote for a regional closed party list of candidates. Additional member's seats are allocated from the lists by the d'Hondt method, to create a more proportional outcome in both the region and the Senedd.
