Initial proposals for new constituency boundaries: Wales

The number of parliamentary constituencies in Wales will fall from 40 to 30 as part of the current boundary review. Provisional proposals for the new seats were published by the Boundary Commission for Wales on 11 January 2012.

This note looks at the extent to which proposed constituencies can be identified with existing seats and which existing constituencies would be most affected by the proposals. The proposals for Wales are also compared with the initial proposals from the Boundary Commissions for England, Northern Ireland and Scotland, published in September and October 2011. Proposals for England, Scotland and Northern Ireland are analysed in detail in separate Library Standard Notes: SN06068 (England); SN06070 (Northern Ireland); SN06098 (Scotland).
