Russia Summons UK Envoy Over Arms Supplies to Ukraine

The protest is notable less for the summons itself than for the framing: Moscow is treating Western arms deliveries as a direct constraint on any negotiated settlement, which effectively links the diplomatic track to decisions made in London and other supplier capitals. That puts the UK, rather than Kyiv alone, inside the diplomatic equation. Whether such protests translate into concrete retaliation or remain declaratory is the open question, and it matters most for the wider set of states weighing continued weapons transfers.
