Kenneth Sydney Vaus (30 September 1928 – 1982) was a British Liberal Party activist.
Vaus attended Haberdashers' Aske's Boys' School and the University of Sheffield, where he qualified as a dentist.[1] He was active in the National League of Young Liberals, and was serving on its executive in 1954/55.[2]
At the 1959 United Kingdom general election, Vaus contested East Surrey; he took second place, with 18.3% of the vote. Herbert Harris, the party's general director, praised his performance as "one of the more remarkable results for us".[3] He stood in Hereford at the 1964 and 1966 United Kingdom general elections, and then Reigate in 1970.[4] By this time, Vaus was serving on the Liberal Party's Executive, and he stood unsuccessfully to become the party's chair in 1970.[5]
Vaus again contested East Surrey in the February and October 1974 United Kingdom general elections, taking 33.8% and 29.2% of the vote and second place to Geoffrey Howe.[6] He was finally elected as the party's chair in 1973, and was still in office in 1976,[7] when party leader Jeremy Thorpe resigned in controversial circumstances. Vaus tried to push through a rule change to allow any MP to stand for the leadership with just a single nomination, hoping that this would get his preferred candidate, Russell Johnston, onto the ballot. His proposal was heavily defeated.[8]
In 1978, Vaus was a founder member of "Liberals Against the Pact", a group opposing the party's pact with the Labour government.[9] He spent some time chairing the party's Finance and Administration Board, a role in which he replaced Clement Freud.[10] In the 1981 Birthday Honours, he was made a Commander of the Order of the British Empire.[11]
Vaus died in 1982, at the age of 54.[12]
