The constituency was abolished as part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales.

Its wards were split between Clwyd East, Dwyfor Meirionnydd, Montgomeryshire and Glyndŵr, and Wrexham.

Main population centres included the suburbs of Ruabon, Chirk, Rhosllannerchrugog, Cefn Mawr and Coedpoeth to the south of the city of Wrexham, in addition to Llangollen and Corwen further up the Dee valley to the west.

Until the 2010 election, the constituency included a small part of the preserved county of Powys.
