The latest round of peace talks in Moscow between the Americans and the Russians has ended without agreement. As President Vladimir Putin talked of being ready to fight a war with Europe, attention in Westminster turned to whether the U.K. has the capability and the will to help protect Ukraine in all scenarios.

While Keir Starmer flew to Scotland to announce a joint maritime operation with Norway  to ward off prowling Russian submarines in the North Atlantic, defense chiefs and MPs asked why there was so little mention of the spending commitments in the Budget — and what that means for Britain’s preparedness.

This week, Anne McElvoy talks to John Foreman, who was Britain’s military attaché in Moscow between 2019 and 2022 having previously performed the same role in Kyiv; and with Esther Webber, POLITICO’s Senior Foreign and Defense Correspondent. Both have been keeping a close eye on the talks.

Later she’s joined by two influential MPs to discuss Starmer’s options. James Cartlidge is the Shadow Defence Secretary, and Labour’s Calvin Bailey sits on the influential Defence Select Committee and served in the RAF for 24 years, including in Afghanistan.
