Sir Keir Starmer has been accused by military experts of hiding behind “cringey” cliches over his plans for a peacekeeping coalition in Ukraine.

John Foreman, a former UK defence attache to Moscow and Kyiv, told The Telegraph there were concerns that the Prime Minister’s initiative was proving hollow and had no clear objectives.

It came as US and Russian officials on Monday began talks in Riyadh to discuss a ceasefire in Ukraine.

Despite 30 nations meeting last week at Permanent Joint Headquarters in Northwood for talks led by Lt Gen Nick Perry, the commander of joint operations, the Government was unable to set out what concrete plans had been made regarding the number of troops and equipment each country could send to Ukraine.

Speaking after the meeting, Sir Keir said the coalition, which was launched on March 2, had moved from “political momentum” to “military planning”.
