No, that's not a proposal of the Law Commission report (which isn't a proposed new law).

Here's the document. It's over 300 pages long. The consultation is still open.

The report gathers information about all the whistleblowing protection law in the UK; all the secrecy protection law (which exists in some weird places; and laws in other countries.

The 14 years comes from 2 places:

1) comparing the English "Official Secrets Act" maximum sentence (currently 2 years) with the equivalent in Canada (currently 14 years). But the report does not propose, even tentatively, that the English maximum is extended to 14 years.

2) Comparing the maximum sentence under the official secrets act with other laws. For example:

> 3.184 The maximum sentence for the offences contained in the Official Secrets Act 1989 is the same as many other offences that criminalise the unauthorised disclosure of information. For example, it is an offence punishable by up to two years’ imprisonment for an employee of the National Lottery Commission to disclose information that has been supplied by Her Majesty’s Commissioners for Revenue and Customs that relates to a person whose identity is specified in the information or whose identity can be deduced from the information. This is the same maximum sentence available for an unauthorised disclosure that, to take one example, damages the capability of the armed forces to carry out their tasks.

One effect is to lengthen the maximum sentence under the Official Secrets Act, but another might be to reduce the sentences in all these other laws.
