Bordāns said Harmony, nominally 'social democratic' but on many issues far from the European social democratic mainstream, has been ruled out as a coalition partner due to perceived pro-Kremlin leanings.
Bordāns told Latvian Radio he expects his party to win 20 to 40 seats at the 13th Saeima, though the latest polls put party support at a modest 3.9%, under the 5% threshold required to make it into the Saeima.
"It's a realistic number," said Bordāns, claiming that a survey carried out by the party puts electoral support for JKP at 10%.
Earlier JKP said it was skeptical over cooperating with Latvia's current leading party, the Greens and Farmers Union (ZZS).
Now, however, asked about possible coalition partners if the party makes it past the post, Bordāns appeared to backtrack, saying that his party is open to discussion but it'd still be good to do without ZZS.
"We would be happy if it'd be possible to set up a government without ZZS and Harmony," he said.
JKP was the first party to submit its tickets to the Central Election Commission, with 105 candidates in total. The 13th Saeima election takes place October 6.
