As reported by Censor.NET, he announced it on Thursday in Warsaw, during a press conference with Polish Prime Minister Beata Szydło.
"The United Kingdom is firmly committed to protecting the security of NATO's eastern flank. The Royal Air Force regularly participates in the Baltic Air Policing mission and we have deployed 3,000 troops on training exercises in Poland in the last 15 months alone. But we want to do more," Cameron said.
He stressed that Britain was one of the first countries to contribute to setting up NATO's high readiness joint action task force and that it would advocate the persistent presence of NATO troops in Poland and its neighbors.
Cameron expressed hopes that the coming NATO Summit scheduled for next July in Warsaw would be as much of a success as the previous Wales Summit had been.
