Charles Alfred Cripps, 1st Baron Parmoor, KCVO, PC, KC (3 October 1852 – 30 June 1941) was a British politician who crossed the floor from the Conservative to the Labour Party and was a strong supporter of the League of Nations and of Church of England causes.

Cripps later claimed to have been a supporter of the Liberal Party, but in deference to his die-hard Conservative father, he declined to get involved in politics.

[5] He received a peerage from the Liberal government in 1914 and took the title Baron Parmoor, of Frieth in the County of Buckingham,[6] from the family estate.

Although not a judge, he was specially appointed to the Privy Council[7] and to its Judicial Committee, and was among the members of it which ruled on the case of The Zamora (1916),[8] concerning the owner's rights on requisition of a neutral cargo ship, which he later considered, when sitting as a member of the Judicial Committee of the House of Lords on the government's appeal concerning an owner's entitlement to compensation for requisition of a London hotel, in the case of A-G v De Keyser's Royal Hotel Ltd (1920).

In the aftermath of war, he became very active in international causes, setting up the 'Fight the Famine Council' which had as its secondary objective the establishment of a League of Nations.

Macdonald, who was serving as his own Foreign Secretary, also chose Parmoor as British representative to the Council of the League of Nations, and to its Assembly in September 1924.

He served again as Lord President of the Council with special responsibility for League of Nations affairs in the second Labour government of 1929–1931, despite his advanced age of 76 at reappointment.
