Patient records are at risk from hackers because they are now more valuable than credit card details, NHS bosses have revealed.

Former deputy chair of NHS Digital Sir Nick Partridge said that while there were systems in place to try and combat hacks, the value of personal data meant there was an increased risk.

"Systems are there but there's a growing understanding that patient records are now much more valuable on the dark web than credit card ratings," he said.

"They sell for more money so we can only expect this level of cyber attack to increase in a very fragmented NHS and it's going to be a growing challenge".
