It was won by the Conservative Party candidate Ronald Nall-Cain.
The Conservative candidate was Ronald Nall-Cain, a wealthy barrister and a Hertfordshire County Councillor, while the Labour Party selected S.L.
The Liberal candidate had won nearly 30% of the vote at the 1929 general election, but the party did not contest the by-election.
Most of the Liberal vote went to the Conservatives, and on a reduced turnout Nall-Cain held the seat with a massively increased majority.
Nall-Cain was re-elected at the general election in October 1931, and held the seat until the death in late 1934 of his father Charles, whom he succeeded as Baron Brocket, triggering another by-election.
