Boris Johnson is among those receiving direct security updates on individuals prepared to “undermine national health security”.

The movement’s more extreme elements are recruiting and strategising over the encrypted social media messaging app Telegram, with one UK anti-vaxxer channel asking for “men of integrity” to “fight for our children’s future”…

Of chief concern is that Britain’s anti-vaxx conspiracists are moving offline, with the UK-based Alpha Men Assemble (AMA) group organising military-style training in preparation for what it has termed a “war” on the government and its Covid policies.

Recent posts from the AMA’s official Telegram channel, which has 7,000 subscribers, encourage members to adopt anti-surveillance techniques by using “burner phones” and advise people to “communicate off line” with CB and ham radios.
