The Government and NHS bosses are facing growing questions over why hospitals across the country were crippled by a global cyber attack amid suggestions preventative measures could have been taken 'months ago'.
The health service faces a weekend of chaos after the unprecedented attack forced hospitals to cancel and delay treatment for patients.
Doctors reported seeing computers go down "one by one" as the "ransomware" took hold on Friday, locking machines and demanding money to release the data.
The National Cyber Security Centre said teams were "working round the clock" in response to the attack as it was reported up to 99 countries, including the US and Russia, were hit.
Prime Minister Theresa May said the Government is not aware of any evidence patient records had been compromised.
"This is not targeted at the NHS, it's an international attack and a number of countries and organisations have been affected," she added.
However shadow health secretary Jonathan Ashworth said the attack was "terrible news and a real worry for patients" and urged the Government to be "clear about what's happened".
