With its majestic mountains and stunning countryside, Brecon and Radnorshire has long been a draw for outdoor enthusiasts.
Unsurprisingly, many of those living in this sparsely populated, rural constituency work in agriculture.
Farming union NFU Cymru is headquartered at the Royal Welsh showground in Llanelwedd, Powys.
Its president, John Davies, who lives in the village of Merthyr Cynog, said farming was the biggest issue here.
Geographically, Brecon and Radnorshire, which covers a swathe of mid Wales, is the largest constituency in England and Wales.
