The Unionists selected 29-year-old Mungo Murray to defend the seat. He was the son of Lord Mansfield. A graduate of Oxford University, he had served in the Black Watch. He was standing for parliament for the first time.
The Labour Party needed to select a new candidate as their last candidate, the former MP, Joseph Sullivan, had been elected at the 1926 Bothwell by-election. Sullivan had been a prominent figure in the Lanarkshire Miners Association and local Labour Party would have liked to choose another miners representative. However, they settled on Miss Jennie Lee, a teacher from Fife and a graduate from Edinburgh University. She was standing for parliament for the first time.
