The Union of Liberal Students (ULS) was the English and Welsh student wing of the United Kingdom's Liberal Party. The Scottish Liberal Party had a separate organisation, Scottish Liberal Students. Together with the party's youth wing, the National League of Young Liberals (NLYL or Young Liberals), the organisations made up the Young Liberal Movement.
ULS was founded in 1920 as the Union of University Liberal Societies and merged with the student wing of the UK Social Democratic Party when the parent parties merged.
ULS was a member of both IFLRY and LYMEC.
In 1966 Liberal, Communist and independent students formed the Radical Students Alliance with the intention of introducing a more active, grass-roots approach to student politics. In 1969 Jack Straw was elected to the NUS executive as a Radical Students Alliance candidate.
The RSA was dominant in student politics until 1971 when the Broad Left (an alliance of Communists and Labour Students) came to prominence.
During the 1970s ULS had little success in NUS National Executive elections with Francis Hayden (1975), Gavin Grant (1978) and Leighton Andrews(1979) being the only electoral successes as part-time Executive members.
In 1979 ULS was one of the founders of the Left Alliance along with Communist, independent Labour (not in the National organisation of Labour Students) and independent members. 1980-82 was a period of Left Alliance leadership of NUS with David Aaronovitch as President of NUS and Jane Taylor as National Secretary.
In 1982 John Murray was elected as a part-time Liberal/LA member of the NUS Executive along with Frank Howard (Labour/LA) and Kate Steele (Communist/LA). John later went on to be National Treasurer of NUS.
