Research by consumer group Which? has found that Brecon and Radnorshire is the hardest hit constituency in Wales by bank closures, with 14 branches shutting their doors since 2015.
Thomas Docherty of Which? said that because 40% of households in the area couldn’t access the minimum speed of broadband, there was "a double whammy of less bank branches and not being able to use alternative forms of banking services.”
“Towns across Brecon and Radnorshire, from Rhayader to Crickhowell, have been gradually abandoned by the big banks," said Jane Dodds, the local Welsh Lib Dem parliamentary candidate.
"Their actions are leaving our most elderly and vulnerable neighbours isolated, and local businesses to wither on the vine."
A recent House of Commons report suggested that banks should be required to provide and fund ‘banking hubs’ in the local Post Office, with adequately trained staff, in cases where the last bank in town is due to close.
Jane Dodds and the local Lib Dems are joining those calls to ensure that communities across Brecon and Radnorshire are able to access the banking services they need.
“They all play the same game," she said, "pushing customers onto the publicly funded Post Office which has neither the expertise nor resources to deal with anything beyond the most basic of queries."
“I and the Liberal Democrats demand better than the big banks’ neglect of our communities. That’s why we believe that if banks decide to close the last branch in town, they should be forced to set up and fund banking hubs in local Post Offices.”
