The Labor and Yesh Atid parties on Monday signed the first surplus vote treaty for the upcoming general Knesset elections.

A common practice in Israeli elections, a surplus vote treaty means that any “extra” votes — votes that are over the threshold for the final number of Knesset seats but below the threshold to receive another seat — are pooled between the two signatory parties in the hopes that together there will be enough to gain another seat for one of them.

The details of the agreement between the parties were not immediately released. Ynet reported that the agreement left Tzipi Livni’s new Hatnua party out in the cold. The self-styled centrist party would likely be forced to sign an agreement with a party on the far left such as Meretz.
