liberal-unionist

from The Century Dictionary.

• noun A member of that section of the Liberal party in Great Britain which from 1886, refusing to concur in Mr. Gladstone's policy of conceding home rule to Ireland, advocated the maintenance of the legislative union of 1801 essentially unimpaired, and therefore, from the importance they attached to the Irish question, made common cause with the Conservatives.
• Of or belonging to the political party or section of the Liberal-Unionists.
