The Scottish Party emerged in November 1932 as a breakaway from the Cathcart Unionist Association in Glasgow.
In June that same year, members of the Association had set up an 'Imperial Committee', which was a pro-Scottish Home Rule front.
This provoked outrage amongst the leadership of the Unionist Party, who were opposed to the establishment of a Scottish Parliament.
[2][1] McDowall and Gibb were able to enlist the support of James Graham, 6th Duke of Montrose (who became the party's chairman) and Sir Alexander MacEwen, both champions of moderate Home Rule.
Broadly, the Scottish Party consisted mainly of Unionist and Liberal elements (a mixture of lairds, provosts and business people).
