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

France (Tchap/DINUM, now a Matrix.org Foundation member), Germany (BwMessenger), Belgium and Sweden run Matrix-based sovereign messengers; over 25 countries deploy Matrix. UK representatives attended the 2025 Matrix Conference, but 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 yet 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/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, but no UK procurement route or civil-society offer exists and no dated trigger makes it acute.
