Sir Sydney Walter John Robinson JP (27 May 1876[1] – 17 November 1950) was an English farmer, building contractor and Liberal politician.

He first contested Essex South East at the 1918 general election but lost his deposit in a three-cornered fight with the successful Coalition Conservative and Labour Party candidates.

[4] During his time in Parliament Robinson was best known for his introduction of a Bill to include farm workers in the National Unemployed Insurance scheme.

[6] During the 1924 general election the Conservative Party enjoyed a revival of fortune nationally and Robinson could not hold his seat in a three-cornered contest with Tory and Labour opponents.

He came second to the new Conservative candidate Sir Henry Curtis-Bennett with the Labour man, Major Nils Moller losing his deposit.

[10] Curtis-Bennett resigned his seat in 1926 for personal reasons in the wake of his marital problems, soon to end in divorce, citing great strain on his health.
