Montgomeryshire (UK Parliament constituency)


Montgomeryshire is a constituency represented in the House of Commons of the Parliament of the United Kingdom. Created in 1542, it elects one Member of Parliament, traditionally known as the knight of the shire, by the first-past-the-post system of election.
The Montgomeryshire Welsh Assembly constituency was created with the same boundaries in 1999.

Boundaries

The seat is based on the ancient county of Montgomeryshire, in the principal area of Powys. One of Britain's most rural and isolated constituencies, Montgomeryshire elected Liberal or Liberal-affiliated candidates from 1880, until a Conservative victory in the 1979 general election. In the 1983 general election it was only seat in England and Wales where a sitting Conservative MP was unseated, while nationally his party's seat majority increased. However, in 2010, the Conservatives won and held the seat in 2015 and 2017, with an increased majority. The seat is believed to be marginal, but the figures show that this is not the case. The seat was officially known as Montgomery before 1997. It is the only seat in Wales never to have elected a Labour MP.
Until 1918 this seat, in common with many others, contained an enclaved seat which was comprised the boroughs of Montgomery, Llanfyllin, Llanidloes, Newtown and Welshpool. This seat survived the Redistribution of Seats Act 1885 which abolished many similar seats. The seat was finally abolished in 1918 and absorbed into the wider Montgomery seat where it remains today.

Proposed constituency changes

Under proposed constituency boundary changes announced in September 2016, ahead of the next general election, the seat was to be partitioned, the northern half including Welshpool to be merged with Clwyd South to form a new seat of South Clwyd and North Montgomeryshire; most of the southern including Newtown will be merged with the Brecon and Radnor seat to form a seat renamed as Brecon, Radnor and Montgomery, and the wards of Llanidloes and Blaen Hafren merged into the Ceredigion constituency which would form part of a new seat called Ceredigion and North Pembrokeshire. However, the general elections of 2017 and 2019 were fought on existing boundaries.

In 1983 this was Labour's worst performance in Wales and the only seat where Labour won less than 12.5% and lost their £150 deposit. The threshold for retaining deposits was lowered to 5% in 1985.
