Dublin City by-election, 1870

The Dublin City by-election of 1870 was fought on 18 August 1870. The by-election was fought due to the void election of the incumbent MP of the Conservative Party, Sir Arthur Edward Guinness. The election was voided because of his election agent's unlawful efforts, which the court found were unknown to the candidate.

It was won by the Liberal candidate Sir Dominic John Corrigan.

Corrigan did not stand for re-election in 1874; his support for temperance and Sunday closing (of pubs) is thought to have antagonised his constituents and alcohol companies. Guinness was re-elected in 1874.
