The opposition Saskaņa (Harmony) party remains the most popular single political force in the country, though its level of support has been falling. In August it commanded 16.1% support but by September this had fallen to 14.5%
Heading in the other direction is the nationalist Nacionālaja apvienība (National Alliance) political grouping which is now occupying second place in voters' affections after growing from 8% support in August to nearly 9% in September.
Third place is held by another opposition grouping, the Zaļo un zemnieku savienība (Greens and Farmers Union, ZZS) which has seen is fortunes rise to 8.4%, narrowly squeezing out Jauna Vienotība (New Unity) on 8.3%.
Interestingly, the three young parties that made breakthroughs during the 2018 Saeima elections are now languishing behind the longer-established parties.
The New Conservative Party has 7.2% support, For Development/For has 6.1% and KPV LV has seen its support collapse to just 2.8%, which would not be enough to win a single Saeima seat if elections were held now.
However, as always with Latvian polls, the results are subject to one huge caveat: 22.1% of voters say they don't know who they would vote for and a further 16.1% say they would not participate at all in an election, meaning that a question mark hangs over well over a third of the electorate.
The SKDS data came from a survey of more than 1,000 Latvian voters carried out between September 6 and 18.
