Banking turmoil: How worried should we be in Britain?

Barclays said in a statement: "As visits to branches continue to fall, we need to adapt to provide the best service for all our customers.

"Where there is no longer enough demand to support a branch, we maintain an in-person presence though our Barclays Local network, live in over 200 locations, based in libraries, town halls, mobile vans and our new banking pods.

"We also support access to cash with our cashback without purchase service, 24-hour deposit-taking ATMs and by working alongside the Post Office and Cash Access UK."
