There were problems with the 20 November 1868 election in the Borough. A petition was presented by the losing candidate, alleging corruption. As a result the election was declared void. Parliament then passed the Sligo and Cashel Disenfranchisement Act 1870 (33 & 34 Vict. c.38). On 1 August 1870 Sligo Borough lost the right to elect its own MP. The area was transferred to form part of the Sligo County constituency.
Last MP for the constituency. Election declared void on petition.
1870, August 1
1 Walker (like F. W. S. Craig in his compilations of election results for Great Britain) classifies Whig, Radical and similar candidates as Liberals from 1832. The name Liberal was gradually adopted as a description for the Whigs and politicians allied with them, before the formal creation of the Liberal Party shortly after the 1859 general election.
