Guidelines for UK cabinet meetings have reportedly been updated to include a ban on the Apple Watch, partly due to concerns about the possibility of Watch-facilitated spying by hackers. The Telegraph reports this policy is an extension of an existing ban on smartphones from similar meetings.

Russian hackers could, as per this concern, use a mobile device to spy on important meetings. If smartphones are going to be kept out, the Apple Watch should also be removed.

Even though a lot of the Watch’s functionality comes from its connection to a phone, spying is theoretically possible. For example, the Watch can work over WiFi networks that it has previously connected to and that could potentially allow some hacking concern to exist.

The ban was reportedly instituted by Theresa May, the current Prime Minister.
