Senedd constituencies and electoral regions

From Simple English Wikipedia, the free encyclopedia
A map of the 40 constituencies and the five electoral regions of Wales.

The Senedd, the unicameral parliament of Wales, has 40 single-member constituencies (Welsh: etholiadau) and five multi-member electoral regions (Welsh: rhanbarthau etholiadol).

The boundaries and names of the 40 constituencies are the same as those in the House of Commons in the Westminster Parliament.
