Operations cancelled as Jeremy Hunt is accused of ignoring warnings

David Wrigley of panel that drew up guidelines on cybersecurity says ministers failed to heed advice last summer

Operations and hospital clinic appointments due to take place on Tuesday have been cancelled amid claims that ministers ignored warnings last year that the NHS could be at risk from cyber-attacks like the ongoing ransomware causing havoc in 150 countries.

Jeremy Hunt, the health secretary, said an anticipated second wave of malware attacks in Britain, that experts had feared might strike on Monday, did not materialise.
