With the 75th anniversary of the establishment of NATO fast-approaching, Leo reflected on the important job they do in keeping its member states safe, as well as Britain's integral role in the alliance.
Commenting on the occasion, Leo said:
Today marks 75 years since the formation of NATO - the most successful defence alliance in history. The UK was a founding member, and our commitment remains unwavering.
"Since becoming an MP, I have had the privilege of meeting with British forces deployed as part of NATO in Estonia and Kosovo, as well as senior figures within NATO itself.
"I pay tribute to all involved in the alliance who help ensure the peace and security of all its members."
