At the Warsaw Security Forum on Tuesday 13 October 2026, UK Foreign Secretary Ed Miliband was expected to back President Volodymyr Zelenskyy's support for an energy ceasefire, according to the Foreign, Commonwealth & Development Office. The department said Russia had mounted 200 attacks on Ukraine's energy infrastructure in the previous week, alongside 1,450 bombs and 1,600 drones fired at Ukraine in the same period, as the country faced another winter.

Miliband was due to speak on a panel with the foreign ministers of Poland, Germany and Norway on hybrid threats from hostile states. He was expected to argue that Russian actions pose an immediate threat to UK security and to call on European partners to mobilise economic, industrial and political strength. The department cited a December 2025 attack on Poland's energy grid that came close to leaving half a million people without power, and a train sabotage the previous month that narrowly avoided mass casualties.

Ahead of the forum, Miliband said he had met children in Kyiv whose winters had been marked by strikes and blackouts, and that unity was the answer to attempts to divide democracies. The department also pointed to a new National Centre for Information Defence, a partnership with Germany on hybrid threats, and more than £300 billion in defence spending over the next four years. In Warsaw, Miliband met Polish Foreign Minister Radosław Sikorski and visited the Jewish Historical Institute.
