Downing Street have said that “nothing is off the table” in terms of possible UK troop deployment for Ukraine, as Western military planning is set to intensify in London next week.

Number 10 said “thousands” of personnel would be required to support any operation whether by “sea, on land or in the air” as allies prepare “for all eventualities” amid diplomatic efforts to end the war.

Officials from the so-called coalition of the willing will “accelerate the pace and scale” of work to consolidate proposals for possible troop deployment across land, air or sea to safeguard any peace deal.

It comes after Sir Keir Starmer warned Vladimir Putin would face “severe consequences” for breaching any truce as he met defence planners for the first stage of talks at the UK’s Northwood military headquarters
