It was the latest occurrence of two by-elections in the same constituency in the same year until the 1990 Bootle by-elections.
Vacancy
Under the provisions of the Succession to the Crown Act 1707 and a number of subsequent Acts, MPs appointed to certain ministerial and legal offices were at this time required to seek re-election.[1] The by-election in Edinburgh South was caused by the appointment of the sitting LiberalMP, Hugh Childers as Home Secretary.[2]
Candidates
Childers had been the MP for Edinburgh South for just a few days when he had to resign to seek re-election. He had won the seat on 29 January 1886 in a by-election occasioned by the death of Sir George Harrison who had been elected as an Independent Liberal at the 1885 general election. At the by-election, Childers beat his Conservative challenger, Walter George Hepburne-Scott, 9th Lord Polwarth, taking 70% of the poll.[3] Before being selected for Edinburgh South, Childers had been MP for Pontefract in the West Riding of Yorkshire since 1860 [4] but had lost the seat narrowly at the 1885 general election.[5]
Having been so roundly beaten so recently in the constituency, the Tories did not wish to contest Childers’ appointment to the government and there being no other nominations, Childers was returned unopposed.[8]
