Henry Usborne was born in Leamington, Warwickshire, educated at Bradfield College and read Engineering at Cambridge.
At the 1945 general election, He was elected as the Member of Parliament (MP) for Acocks Green. The constituency was then abolished and in 1950 Usborne was elected in the marginal constituency of Birmingham Yardley. He held the seat until the 1959 general election.
According to his obituary in the Times on 19 March 1996, Usborne resigned from the Labour Party in 1962 and joined the Liberals. He urged former colleagues to join Jo Grimond's party as the best hope for defeating the Conservatives. There was a suggestion that Usborne be nominated to stand for the Liberal Party at Cheltenham but he announced that wild horses would not drag him into another Parliamentary contest.
In addition to his work as a constituency MP Henry Usborne was one of the main drivers in the British branch of the World Federalist Movement. In 1947, ahead of the foundation of the United Nations, he co-founded the Parliamentary Group for World Government, which as All Party Parliamentary Group for World Governance (APPGWG) counts today (2008) 167 members and meets regularly to provide a forum for debate on global governance issues in the UK Parliament. In 1951 Henry Usborne set up the One World Trust as an independent educational Charity to provide secretarial support to the Group, promote and disseminate knowledge on world governance. In addition to its ongoing support for the APPGWG the One World Trust conducts independent research into the accountability of global organisations, political engagement of citizens at global level, and international law. He died in Evesham aged 86.
