The family business, which has had close links to the Royal family, is set to close its doors in May.

Owners Alan and Kathryn Hughes said it was with a "heavy heart" they have taken the decision to close the business.

It comes as the company saw renewed success due to the hit drama Downton Abbey which saw a surge in orders from American fans for table bells, which were traditionally used to ring for tea.

Despite diversifying into manufacturing doorbells and creating an online store a few years ago, the owners have taken the difficult decision to close the firm.

"We have made this decision with a heavy heart, but in response to the changing realities of running a business of this kind. The Bell Foundry in Whitechapel has changed hands many times, but it has always been a family business," Mr Hughes said.
