At Dartmouth, Litchfield was asked to "keep a fraternal eye" on fellow cadet Prince Charles of Belgium, and later served with him on when it visited the far east with the Prince of Wales. In 1922, while at the wedding of Lord Louis Mountbatten, Litchfield accidentally trod on the foot of former Prime Minister H. H. Asquith, who uttered a response that was "unparliamentary and swift". That same year, it was Mountbatten who personally informed Litchfield of his father's death. Litchfield was appointed as "King's Midshipman" for Cowes Week of 1924, and nearly caused problems when his steamship came within inches of colliding with the Royal Yacht. He later recalled that he heard a loud cry of "Mind my paintwork, boy!" and looked round to see that King George V was glowering at him. Later in the 1920s, Litchfield was called upon to reply to the toast "Wives and sweethearts" while on board Renown carrying the Duke and Duchess of York to Australia. He decided to end with his own toast, to the Princess Elizabeth, and ever after claimed to have been the first person to toast the health of the Queen.
Naval advancement
In 1929, Litchfield was posted to the Yangtze River and won permission to travel via the Trans-Siberian Railway. He stopped off in Moscow to see the sights and when he photographed the Kremlin, was detained by the OGPU as a suspected spy. Litchfield was an enthusiastic photographer, both still and cine, and his footage of naval operations is valued by historians. The 1930s saw him stationed in Palestine commanding armoured cars and trains on the land, and trying to stop Arab terrorists. He was mentioned in dispatches for his work there.
Litchfield was struck down by polyneuritis that year and took six months' sick leave to recover. He ended his naval career as Director of Operations for the Admiralty in 1953–1954, and retired with the rank of Captain in 1955. On leaving he had already decided to go into politics with the Conservative Party and was elected to Kent County Council in 1955, serving for a single three-year term.
Parliament
Having determined to try to enter Parliament, Litchfield was disappointed at Maidstone. However he was selected for Chelsea for the 1959 general election. Chelsea was a very safe seat and his selection was controversial because Litchfield was in his fifties and not likely to become a long-standing member. Nicholas Ridley was the choice of the minority, but Litchfield won many around by his sincerity. He was comfortably elected. During the Profumo affair, Litchfield was among a small group of Conservative MPs who felt that Harold Macmillan had been mistaken in keeping Profumo in the government following his denial of any impropriety. However, Litchfield liked Profumo personally. During a Parliamentary trip to NATO headquarters, Litchfield found that all the seats in the limousines were taken, and was forced to travel sitting on Harold Wilson's lap.
Retirement
As suspected by the Chelsea selectorate, Litchfield would not have a long Parliamentary career, retiring in 1966. He continued making films, and was pleased to loan one of his films on the Russian convoys to Captain Jack Broome who used it to win a libel action against author David Irving. He was also a raconteur who used his store of stories of his naval career to entertain audiences.
