In January, 1919, a successful trial of proportional representation was made in the municipal elections of Sligo, and in the following July a local government (Ireland) act extended the system to all Irish municipal elections. The form employed is the Hare plan, the “single transferable vote,” as it is usually called in the United Kingdom. On January 15, 1920, the first general trial of the new scheme was made, when elections were carried out in 127 Irish municipalities.
