The government's policy on email encryption is still flawed, a group of MPs has warned.
Liberal Democrat Richard Allan, chairman of the Parliamentary All-Party Internet Group, told Radio 4's Today programme that many MPs and civil servants were unaware of how easy it is for emails to be read by the wrong person.
Ministers have been warned that urgent steps are needed to improve awareness among MPs and civil servants over which emails are secure and which are not.
Although the government has a secure intranet system, as soon as emails are sent outside that system they are at risk of being intercepted and read, Allan said.
Encryption systems needed to be more widely promoted by government, he added. "We need some form of encryption that everybody can share, whether it is local authorities, private citizens or the government."
