A former deputy director for Intelligence and Cyber Operations at GCHQ has said it is "extraordinary" that a number of large corporations "haven't put up-to-date patches into place" to protect themselves from the spread of a cyber-attack.

Brian Lord, who now runs the cyber security company PGI, told Eddie Mair that after the Wannacry attack last month a patch was created that "would have limited the spread of the new ransomware".

He said corporations "could have and should have" put patches into place.
