Midlothian by-election, 1912

The Midlothian by-election was a Parliamentary by-election. It returned one Member of Parliament to the House of Commons of the United Kingdom, elected by the first past the post voting system.

The Master of Elibank had been Liberal MP for Midlothian a.k.a. Edinburghshire, since 1900. He was raised to the peerage as Baron Murray of Elibank, in the County of Selkirk.

The Liberal candidate chosen to defend the seat was Alexander Shaw. He was a 29-year-old Barrister who had been educated in Edinburgh. The Unionists again selected John Hope who had fought the seat at the last election. He was a 43-year-old soldier. The Labour party, which had never before contested the seat, fielded Robert Brown. He was a local man, having been elected Provost of Dalkeith. He was also Secretary of the Scottish Miners Federation. When the vacancy became known, the Unionists quickly re-adopted Hope to enable them to immediately start the campaign. Arthur Henderson the Secretary of the national Labour party met the Scottish Miners Federation, where it was agreed that a Labour candidate would contest the seat. It was clear that this was likely to be Provost Brown. The Liberals were expected to adopt Shaw, however, the outgoing Liberal MP, the Master of Elibank, felt that the Liberal Association should not field a candidate but support Brown, who had strong Liberal sympathies, if he was the Labour candidate. Elibank's telegram to the Chairman of Midlothian Liberals, in which he outlined his views and praised the qualities of Brown, was made public. Elibank had just stepped down as Liberal Party Chief Whip, so was still close to Liberal Prime Minister, H. H. Asquith. However, the Midlothian Liberals decided to select Shaw and Brown was selected by Labour, so a three-way contest was assured.
