No UK public-sector or civic deployment of sovereign messaging (a UK 'Tchap')

France runs Tchap through DINUM, now a Matrix.org Foundation member, Germany runs BwMessenger, and Belgium and Sweden run their own; over 25 countries deploy Matrix-based sovereign messengers. UK representatives attended the 2025 Matrix Conference, and there is no UK procurement, no Crown Commercial Service framework, and government business still runs over WhatsApp, criticised by the Covid-19 Inquiry. Element, the leading vendor, is a UK company earning almost entirely abroad. Nothing offers councils, unions, co-ops or mutual-aid networks affordable managed homeservers.

The UK invented the protocol its allies use for sovereign communications and buys none of it, exporting the industrial benefit and leaving its own public and civic sectors dependent on US platforms subject to foreign legal process.

A GDS and CCS pilot of a Matrix-based government messenger, UK government membership of the Matrix.org Foundation, and a subsidised managed-homeserver service for civil-society organisations.

// Build together: Counterparty: GDS/CCS for the messenger pilot; Matrix software exists and no new law is required.

The instrument is off the shelf and allies already deploy it, and no UK procurement route or civil-society offer exists, with no dated trigger making it acute.
