The Unionists selected 29-year-old Mungo Murray (later Lord Scone) to defend the seat. He was the son of Lord Mansfield. A graduate of the University of Oxford, he had served in the Black Watch and stood 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 have chosen another miners' representative. However, they settled on Jennie Lee, a teacher from Fife and a graduate of Edinburgh University, who stood for parliament for the first time.
The local Liberal Association selected 49-year-old Elizabeth Mitchell as their candidate. She had contested Lanark at the 1924 general election, and was the daughter of Andrew Mitchell, a former sheriff of Lanarkshire and a member of Lanarkshire Education Authority.[1] She had been educated at St. George's School for Girls, Edinburgh, Edinburgh University, and Oxford University, and taught at the Royal Holloway College, University of London. She was honorary secretary to the Committee on Women in Agriculture in Scotland, convener of Continuation classes at the County of Lanark, and vice-president of the Scottish Liberal Federation.[2]
On 1 March, nationally, Liberal leader, David Lloyd George launched the Liberal programme for the upcoming General Election, titled We Can Conquer Unemployment.
