Companies can do the old man in the middle where by each device has an encrypted connection to the company's server and the company server decrypts the sender's traffic and log it before re-encrypting it and sending it to the receiver. This method doesn't rely on back doors or breaking encryption. Meaning the data is secure in transit. It does mean that every government agency will have access to the logs as well as people working in the company. Which is basically what your government seems to want. I think if the UK pushes forward with this using law, this will be the likely implementation for any vendors that wish to operate in the UK. What's more I think most people will be fine with this approach as well. This Rudd woman seems to be an imbecile.
