Hundreds of jobs are under threat at Byron after the stricken burger chain put 20 restaurants - including the one in Windsor - at risk of closure as part of a proposed restructuring package.

The burger chain hopes to agree a company voluntary arrangement (CVA) allowing it to close loss-making stores, a process recently used by embattled toy retailer Toys R Us.

But the plan will need to win the backing of landlords and creditors before it can go forward.

The Windsor branch of the chain opened in Thames Street opposite the castle in October, 2016.

Byron, which was founded by Tom Byng in 2007, employs around 1,800 people and has 67 leasehold restaurants and nine non-operational leasehold sites across the UK, including its head office in London.

Simon Cope, Byron chief executive, said: "Byron's core restaurant business and brand remain strong but the market that we operate in has changed profoundly.

"In order to continue serving our loyal customer base, we need to make some critical and difficult changes to the size and shape of our estate.

"With the support of our new owners, our creditors, landlords and other business partners, I'm confident Byron will able to continue providing our consumers with the best burger experience.

"The teams in our restaurants are always such an inspiration and we will work hard to support them throughout this difficult process."

Byron will need 75% backing from creditors if the CVA is to succeed, with the vote taking place on January 31.
