If you've worked for Morrisons, you could be due a compensation payout.

The Bradford-based supermarket chain today lost its appeal against a ruling that found it is liable for a massive breach of its payroll data in 2014.

Morrisons has said it will appeal the decision again, this time to the Supreme Court - the highest court in the land - but if it loses this hearing, it will have no choice but to pay out.

What happened?

In 2014 an internal auditor at the firm, Andrew Skelton, leaked the firm's payroll data onto the internet - including the names, addresses, bank account details and salaries of thousands of staff. He was sentenced to eight years in prison.

Who could be in line for compensation?

If you worked for Morrisons or its subsidiary companies Kiddicare, Farmers Boys or Woodhouse Bros during 2013, your personal information could have been included in the leak. More than Today's High Court ruling means that everyone whose data was stolen could potentially claim compensation.

What do you need to do to claim?

More than 5,000 staff have already brought a class action against Morrisons in the case that led to today's Court of Appeal ruling, but more than 100,000 people's data are thought to have been leaked in total. Today's ruling means they could all potentially sue Morrisons for damages.

The claims are being handled by JMW Solicitors, and if you think you could be affected you should get in touch via the dedicated page on their website.

What do the solicitors say?

Nick McAleenan, a partner and data privacy law specialist at JMW, said: "This case involves a significant data leak which affected more than 100,000 Morrisons employees - checkout staff, shelf-stackers, and factory workers; hard-working people on whom Morrisons' entire business relies.

"They were obliged to hand over sensitive personal information and had every right to expect it to remain confidential, but a copy was made and it was uploaded to the internet and they were put at risk of fraud, identity theft and a host of other problems. Unsurprisingly, this caused a huge amount of worry, stress and inconvenience.

"The claimants are obviously delighted with the Court of Appeal's ruling. The judges unanimously and robustly dismissed Morrisons' legal arguments."

"These shop and factory workers have held one of the UK's biggest organisations to account and won - and convincingly so. This latest judgment provides reassurance to the many millions of people in this country whose own data is held by their employer."
