Isle of Anglesey electoral boundary changes 2012

The Isle of Anglesey electoral boundary changes in 2012 reduced the numbers of electoral wards to the Isle of Anglesey County Council from 40 to 11. This led to the postponement of local government elections in the county by 12 months. The changes were confirmed by the Isle of Anglesey (Electoral Arrangements) Order 2012 in October 2012.

The changes were based on proposals by the Local Government Boundary Commission for Wales, after a review was ordered by the Welsh Government's Minister for Social Justice and Local Government, Carl Sargeant, in March 2012. The Commission proposed replacing the 40 electoral wards, which had elected one county councillor each, with eleven multi-member wards electing 30 county councillors in total. This was ostensibly to bring the ratio of councillors closer to 1:1750 of the voting population. The proposals were revealed by the Boundary Commission in May 2012. Despite strongly opposing the changes, Anglesey County Council voted by a majority on 27 June to accept the proposals and, in September, the Wales Government agreed to enshrine them in law.

As a result of the changes, Sargeant announced in January 2012 that the county council election which was due to take place in May 2012 (at the same time as other United Kingdom local government votes) would not take place until May 2013.
