First Sea Lord

First Sea Lord, officially First Sea Lord and Chief of the Naval Staff (1SL/CNS), is a statutory position in the British Armed Forces, held by an admiral or a general of His Majesty's Naval Service. As the highest-ranking officer in the Naval Service, the chief is the principal military advisor on matters pertaining to the navy and a deputy to the Secretary of State for Defence. The CNS is also a member of the Chiefs of Staff Committee and, thereby, a military advisor to the National Security Council, the prime minister and the monarch. The First Sea Lord is typically the highest-ranking officer on active duty of the Royal Navy unless the Chief of the Defence Staff is a naval officer. The post is currently held by General Sir Gwyn Jenkins.
