The current boundaries have been effective since the Welsh Assembly election, 2007 and the 2010 United Kingdom general election. Very, in relative terms, minor boundary changes occurred from the previous scheme and no name changes.
Changes proposed in 2016
As part of the Sixth Periodic Review of Westminster constituencies the Boundary Commission for Wales proposed changes to almost all the existing Welsh Westminster constituencies, giving some of them Welsh language names.
