Green Party - House Lords Question - nuclear weapons in space

Posted: 1st October 2026

Orbital weapons of both kinds pose a growing threat to the space-based services Britain and its allies depend on, and any attempt to put nuclear weapons in orbit would be highly destabilising and contrary to international law, the Ministry of Defence stated in a written answer.
Lord Coaker, Minister of State at the department, was answering Baroness Bennett of Manor Castle, the Green Party peer, who asked what assessment the government had made of the danger of orbital weapons, kinetic and otherwise, following what she described as the disclosure by the United States of its aggressive space capacity, and what steps ministers plan to take to prevent a new arms race in space.
